Carbon Steel 3PC Trunnion Electric Actuator Ball Valve Gearbox BS 5351 PN64

Carbon Steel 3PC Trunnion Electric Actuator Ball Valve Gearbox BS 5351 PN64

Design Features:

1. Trunnion-mounted Ball:

The ball is fixed and the seat rings are floating, free to move along the valve axis.

Side load generated by the pressure acting on the ball is abosorbed by bearings.

At low pressure the seat sealing action is achieved by the thrust of the springs acting on the seat rings. As the pressure increase the fluid pressure pushes the seat rings against the ball.

2. Independent ball and stem

The ball and stem are independent to minimize the effect of the side thrust generated by the pressure acting on the ball

3. Anti-Static Design

The electrical conductance continuity between all the metallic conponents is guaranteed and certified.

4. Soft Seat valves:

In valves designed for standard service, a resilient material is inserted into the metal seat holder to provide a soft seating action in addition to the metal to metal seating between the ball and the seat rings

5. Metal Seat Valves

Valves designed for abrasive service or for operation in temperatures that prohibit the use of resilient meterial have seating action provided by the metal to metal contact between the ball and the seat rings. Seating faces are hardface.

6. Fire Safe

Trunnion-mounted ball valves are designed fire safe to API6FA, API607 ,BS6755 Part 2.

7. Actuaction

Hand operated valves are supplied either with a lever or gear operated

Actuacted valve can be supplied with Electrice actuator, Pneumatic Actuactor. Gear operators can be easily removed in-service and replaced with actuactors.

Certified Quality

All of our pressure tests and meterial checks are witnessed by an inspector who signs off on their accuracy. A laminated card is then attached to the valve with each test and material check indicated, as certification to our customer that these procedures have been followed. Eevery valve come with a certificate.
