BW Ends PTFE Seat 300LB Trunnion Mounted Ball Valve

Double Block & Bleed Ball Valve Side Entry 300LB BW Ends

We are able to supply side entry trunnion ball valves designed to conform to API 6D valve standard to meet the valve applications requirements of the onshore and offshore Oil and Gas, Oil Refining and Processing, and Petrochemical industries.

Side entry valves are designed as robust, severe service valves, capable of withstanding operation at high pressure (ANSI #2500) and to provide consistent and reliable zero shut off. These valves are the ideal for emergency shutdown applications for hydrocarbon service.

Grease injection device

For DN150 (NPS 6) & larger the stem and the valve seat are provided with a sealing grease injection device, For DN125 & smaller, we can provide the sealing grease injection device according to customer requirements. When the O-ring is damaged by accident, by injected sealant sealed to prevent the media through the valve seat ring and stem leaks.

Fire safe design

Ball valves ensures 100% pass of the fire safe test. As Ball valve applies two sealed design via O-ring seals and metal graphite spiral wound gasket. When the valve is on fire, non-metallic materials such as PTFE seat seals, gaskets ,O-ring seals,rubber etc will be damaged, meanwhile the outer layer of metal graphite spiral wound gasket provides a secondary seal. When the soft seat is burned, metal seat will automatically form a metal seal with ball under the urging of the spring which will effectively control the internal leakage and external leakage. Valve design fully accords with API 607, API 6FA, BS 6755, JB / T 6899 and other standards,

Sealing Options

Soft seat: Metal to Metal O-Ring seal

Simple structure reliable sealing Applicable to particulate Reliable sealing low torque meet customers' high

wide application low cost. media conditions sealing reliability and low torque requirements

DOUBLE BLOCK & BLEED (DBB)

When the ball is in the closed position, each seat seals off the process medium independently at the same time between the up/down stream and body cavity, it allows bleeding the trapped cavity pressure (DBB) through drain and vent valve. The double block and bleed function make it possible to flush the valve under pressure and verify that the seat are sealing properly.

DOUBLE ISOLATION & BLEED (DIB)

Double piston effect seat, medium pressure, both upstream and downstream as well as in the body cavity, creates a resultant thrust that pushes the seat ring against the ball, valve with double piston effect seat rings require a cavity pressure relief to reduce the build-up of over pressure in the body cavity.
