Ball Valves Installation, Operation And Maintenance Manual

Classification

The ball valves is divided into floating ball valve and trunnion ball valve according to the ball support in the bottom trunnion or seat.

The ball valves is divided into metal seal ball valve and soft seal ball valve according to the surface of sealing material.
The ball valves is divided into top entry, side entry and full welded body type according to the body structure.
The ball valves is divided into 1 pc, 2pcs, 3pcs body in side entry ball valve

Usage and feature
Usage
Series floating ball valve and trunnion type ball valve are used in oilfield, chemical-industrial, power-station for cutting and connecting the pipe.

Válvula de esfera flotante-floating ball valve

Válvula de esfera flotante

Una válvula con la bola flotante (no fijo por un muñón ) en el interior del cuerpo de la válvula se denomina como válvula de bola flotante, se deriva hacia el lado de aguas abajo y empuja fuertemente contra el asiento bajo la presión del medio para asegurar la fiabilidad de sellado. Se ha estructura simple, el rendimiento del sellado bueno, se utiliza generalmente en aplicaciones de presión media o baja.

Tamaño: NPS 1/2 “~ 10” DN15 ~ DN250
Grado de la presión: Clase 150 ~ 600 ~ PN16 PN100
Conexión: RF, BW, RTJ, SW, etc
Material: CS, SS, aleación y así sucesivamente
Diseño y fabricación: API 6D, ASME B16.34 (BS5351), API 608, MSS-SP-72

100X type Floating Ball Valve – Product Installation and Maintenance

Water Control Valve Series: Installation and Maintenance of 100X type floating ball valve

Installation and Maintenance

1. Main valve should be installed on the inlet of pool or high water towel. Though other method also able to operate normally, the best way is install valve on the pipe horizontally with the cover upward. Float valve should be installed in the tank or water towel, in order to remote control easily as shown below.
2. Before installation, the pipe should be totally clear up. The valve should be installed follow the arrow direction.
3. 1 pc gate valve and 1 pc filter should be installed before main valve, 1pc gate valve should be installed after main valve, in order to facilitate maintenance.
4. During water test, open the front gate valve slowly so to increase pressure slowly, attention to the leakage of the control pipe outside main valve.
5. In order to pack conveniently, the float valve will be installed in main valve. The actual installation as shown below.
6. The micro filter in the conduit entrance of main valve should be cleaned one time each 2-3 month.

Main valve maintenance instruction

Hydraulic control valve, also named as water control valve, self lubricate by water, it doesn’t require any oil. If the parts of main valve damage, please dismantle the valve follow below instruction. Notes: (Usually the wearing parts within main valve are diaphragm and o-ring. There is little damage for other parts)
1. Close gate valve both before and after main valve
2. Loose the screw in pipe joint of main valve cover, release valve pressure
3. Remove all the screw, including all necessary copper pipe and nut in control pipe.
4. Remove cover and spring
5. Remove stem, diaphragm, piston and so on, not to damage the diaphragm
6. Check if the diaphragm and o –ring is damage, if they haven’t damage, please don’t resolve their internal parts.
