Spring Emergency shut off butterfly valve-quick closing valve

Spring Emergency shut off butterfly valve-quick closing valve 

The emergency shutoff valve or trip valve is used on the above mentioned steam turbines to shut off the flow steam, which is the power source for the turbine in case an overspeed condition of the turbine, or in some cases when the unit is set up for a low oil pressure condition. These turbines are used as general purpose power supplies throughout refineries chemical plants power plants and other areas where steam is generated for heating.

The goal of long term runs more than one year has been desired due to lost production when the turbines are shut down man power required to go through the procedure transferring production to another source and the potential of causing damage to the turbine during shut down and start up.

SGV Quick closing valve is a Spring Emergency shut off butterfly valve which is Electric-hydraulic operated, can be closed within 0.5~1 second.The valve is applied to parrallel generator sets. It shut immediatedly as the accident happens, to prevents the steam and condensed water flowing back and destrying the sets.

This Fast closing valve is mainly used in coal gas residual heat power generation system and extration steam turbine system. The valve is critical auxiliary equipment for system. it can instead of electric cut off buuterfly valve and check butterfly valve because of its small flow resistance and sper seal function.

Valve body and seal structure adopt ADMAS type seal structure, triple offset metal seated butterfly valve.Open and close handily and without leakage.For normal applicaiton, soft seat might be suitable and seal performance can be credible.

Quick closing butterfly valve adopts hdraulic spring or hydraulic accumulator actuators. Both two types are safely and credibly.

Both two kinds operation valve have two stage of close:fast close stage and slow close stage. At the end of closing stage, the valve will be close slowly, so to reduce water hammer and avoid slamming. This design prolong the equippments servive life.

The price of this valve is just about 30% percent of imported western similar products.

High performance Butterfly valve

High performace butterfly valve is just a adjective, never a noun most people used for.Let’s start with what is a butterfly valve? A butterfly valve is from a family of valves called quarter turn valves. It’s name is come from butterfly type structure. The “butterfly” is a metal disc (normal, though now we have plastic valve or other non metal material valve)mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is open, the disc is rotated a quarter turn so that it allows unrestricted passage. The position of the disc is effected from outside the valve.

Butterfly valves are generally favored because they are lower in cost to other valve designs as well as being lighter in weight, meaning less support is required. The disc is positioned in the center of the pipe, passing through the disc is a rod connected to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow.

There are different kinds of butterfly valves, each adapted for different pressures and different usage. SGV, from china, divided mainly two kinds of valve.The resilient butterfly valve, which uses the flexibility of rubber or Tefelon ,PFA, NYLON, has the lowest pressure rating. They are usually center disc design. Typically used for low pressure, normal temeprature condition.

Usually, the other type is metal seated butterfly valve, often appear with double eccentric design or triple offset design. It is developed from tradional center line butterfly valve. Somebody call it high performance butterfly valve, used in slightly higher-pressure systems, features a slight offset in the way the disc is positioned, which increases the valve’s sealing ability and decreases its tendency to wear. The valve best suited for high-pressure systems is the tricentric butterfly valve, which makes use of a metal seat, and is therefore able to withstand a greater amount of pressure, high temperature, corrosive and aggressive chemicals. So-called “High Performance” butterfly valves which offer zero leakage designs and have been applied in both the chemicals and hydrocarbon processing sectors.

Butr some valve manufacturer or supplier also call eccentric PTFE or RPTFE seat butterfly valve as high performance butterfly valve.Like Nibco from American, www.nibco.com

Also there are many other Europe or america butterfly manufacturer and supplier has their own description or definition for high performance butterfly valve.

CRANE from American www.craneco.com

Masoneilan* High Performance Butterfly Control Valves from GE energy , www.ge-energy.com
The high performance butterfly valve delivers heavy-duty, automatic throttling control flow for applications involving large flow rates and moderate pressure drops. It incorporates the two basic features of the high performance butterfly valve types: a PTFE, RTFE, or metal seal ring instead of a liner and double offset (eccentric operation) to reduce seal friction and operating torque and provide superior performance compared to conventional butterfly valves.

High Performance Butterfly Control Valves from GWC Valve International, Inc. www.gwcvalve.com
GWC Double Offset High Performance Butterfly valves are designed for shutoff and throttling control of liquids and gas.

EBRO-armaturen from German
Wafer type butterfly valve in double-eccentric construction. Reliable sealing even with extreme temperature and pressure conditions.

ADMAS triple eccentric butterfly valve from German www.ad mas-armaturen.de
The first triple eccentric metal seat butterfly valve manufacturer.

Usually these words are used for to descript high performance butterfly valve:High performance, low friction, low torque, metal seat(sometimes PTFE or RPTFE seat), eccentric design, long service life, suitable for aggressive condition, high cost performance, bi-directional. There is no words to digital or data to definie what is a high performance butterfly valve. It is no apparent differences between high performance butterfly valve and normal metal eccentric butterfly valve.

So is there any diferences between high performance butterfly valve and normal metal eccentric butterfly valve?  Usuallly high performance butterfly valve is machined by CNC machine with high accurancy, especially some trim parts. It require better quality control and material class. Many valve experts think the valve should reach some degree service life. For example, pass 1 million times open close service life test.

In a word, high performance butterfly valve is a word people descrip valve with very good quality for high requirement application.

Stainless steel valve-API602/API600/API6D-gate,globe,check,ball valve

Stainless steel valve-API602/API600/API6D-gate,globe,check,ball valve

A stainless steel valve is a valve, mainly made of stainless steel, which regulates the flow of a fluid, corrosive or noncorrosive (fluidized solids, slurries, gases, liquids,) by opening, closing, or partially obstructing various passageways. It is a pipeline fluid distribution system control unit, is used to change the channel cross-section and media flow direction for fluid guidance, regulating, cut-off, throttling, stopping and depressurization through diversion or excess flow.

There are many kinds of fluid control valves with various specifications, such as cut-off valves with simplest structure and valves with highly complex automatic control system, minute gauge valves and valves with 10m nominal diameter for industrial pipes.

The types of stainless steel used for valve body are typically appear with CF8, CF3, CF8M and CF3M(or their relevant forge material 304, 316, 304l,316l) these austenitic stainless steel and other special stainless steel include Duplex, Moniel, Inconel and so on.

here are kinds of the stainless steel valves divided by their structure, such as stainless steel gate valve,  check valve,  globe valve, ball valve,  butterfly valve, plug valve, safety valve, baiting valve, steam trap, needle valve, strainer,  air-operated valve and so on.

Stainless steel valve has their application scope:
Its application medium: water, steam, oil, gas, mud, all kinds of corrosive media, liquid metal and radioactive fluid , micro-alkyl, methane, ethane, fresh, ethane, …liquid heavy component ,hydrogenated liquid and so on;
Its Working temperature:-269℃~1430℃;
Its working pressure: 0.0013Mpa~1000Mpa;
It can be operated by many means: such as manual, worm gear, hydraulic, pneumatic, electric, electro-magnetic action, electric-hydraulic, pneumatic-hydraulic, electro-magnetic-hydraulic, spur-gears-drive and umbrella-gear-drive etc. It can react to pressure, temperature or other as required or start or stop without instruction of those sensing signals. Besides, the valve relies on drivers or automatic parts to enable gate parts lifting, sliding, rotating pendulum, rotation, thereby changes the area of the flow channel.

Due to stainless steel have good performance in temperature-dependent yield strength, usually stainless steel valve can have more thin thickness compare with other carbon steel valve  like API600 or API6D. For SGV general and traditional steel gate globe check ball valve, we offer more choice for guest. We have our own mold special design for API603 standard to meet client’s specific requirement to reach highest cost performance.
