Forging trunnion ball valve of 2"-56" CL150-2500 emergency sealant injection
Production, transportation, storage and processing of oil and gas require the highest quality piping components. This is our world. In conjunction with our sister companies we supply customers with valves, hammer unions, couplings, connectors, actuators and other valve accessories
for high pressure process and piping at oil and gas facilities, both above ground and offshore.
2. World Class & Worldwide Service
We are dedicated to providing our customers with the best — the best brands, the best service and the best quality. Whether you require an automated valve for a highly engineered project or a replacement valve delivered same day, we are here to help. Our industry
experience, product selection and access to a global network of partners enable us to tailor a solution to solve your most difficult problem.
3. Expanding Our Product Portfolio
While others are collapsing their portfolios and cutting costs, we have an aggressive strategy to supply complimentary products to served markets
and increase service levels to establish ourselves as your single source provider for valve and flow control solutions.
Positive stem retention is achieved with integral T-type shoulder retained by the gland retainer
Positive anti-static grounding between the ball, stem and trunnion is a standard feature on the Trident Series. Valves sizes 16” and above are equipped with an additional anti-static spring on the trunnion shaft for added safety and reliability.
The double sealing design of the O-Rings and fire safe graphite gaskets ensure zero leakage at the body and closure connections
Valves are equipped with sealant injection fittings at the stem and seat area. The seat injection fittings have an integral buried check valve to provide backup sealing. Should leakage occur at either the seat or gland packing area, leakage can temporarily be stopped by injecting sealant into the secondary sealing system.
Fire safe construction is standard on all trunnion mounted ball valves. In the event of a fire, secondary graphite seals and gaskets prevent leakage to atmosphere and seat ring to ball contact minimizes through leakage.
In very low line pressure applications, sealing between the seats and ball is achieved by seat springs forcing the seat into the ball, resulting in
a seal. In high line pressure applications, the line pressure, in conjunction with the spring load, forces the upstream seat ring against the ball resulting in tighter sealing. The Trident Series’ standard seat design is a selfrelieving seat, which prevents cavity pressure buildup by automatically relieving the cavity when the pressure becomes too high. In the case of leakage past the upstream seat, the optional double
piston effect seat (DPE) has an added benefit of enabling the downstream seat to maintain a tight shutoff seal against the ball.
