Design
steel ball valves are designed manufactured to provide maximum service life and dependability. All ball valves are full ported and meet the design requirements of American Petroleum Institute standard API 608&API 6D British standard BS 5351 and generally conform to American society of Mechanical Engineers standard ASME B16.34 valves are available in a complete range of body/bonnet materials and trims.
Range of Materials
Standard body/bonnet materials include nine grades of carbon, low alloy and stainless steel, for special applications they can be supplied in other grades of ally and stainless steel, there’s a full range of trim materials to match any service optional packing and gasket materials are available for a full range of service conditions.

• BLOWOUT PROOF STEM        

Positive stem retention is achieved with integral T-type shoulder retained by the gland retainer
 

• ANTI-STATIC DESIGN

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.
 

• BODY SEALING

The double sealing design of the O-Rings and fire safe graphite gaskets ensure zero leakage at the body and closure connections
 

• EMERGENCY SEALANT INJECTION

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 CERTIFIED

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.
 

• SEAT DESIGN

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.
