Severe Service Valves

Pressure classes up to 900# ANSI:

• Full port standard with optional regular port.
• Available up to 20" bore.
• Optional Coorstek Ceramic trim.
• Available as uni-directional or bi-directional.

• ISO standard actuator bolt pattern for easy automation.
• Outer stem bearing gives positive stem alignment.
• Live loaded articulating gland flange prevents stem binding and ensures packing will seal even when consolidating over time.
• Blowout proof stems are standard on all SST Valves.
• Belleville spring keeps sealing system in constant contact at all times.
• Mate lapped ball and seats are self wiping to minize solid buildup.   Replaceable balls and seats extends valve life while keeping overall costs down.
• Metallic inner stem seal bearing provides smooth operatin and secondary sealing.
• Engineered body gasket provides low cost reliable seal.
• Stainless steel seat landings in carbon steel valves keep costs down and sealing integrity high.
• Retaining ring keeps seat in place on bi-directional valves when flow changes direction.
