WKM DynaSeal 310 floating ball valves satisfy a wide range of applications and are available in a variety of standard and optional materials, in sizes from 1/4” (8 mm) to 4” x 3” (100 mm x 80 mm) and working pressures to 5000 psi. Engineered for heavy-duty, maintenance-free performance, the DynaSeal 310 ball valve is preferred for use in critical applications.
Sour Oil and Gas Service
WKM DynaSeal ball valves are suited to applications within gathering lines, manifolds and field processing units in sour oil and gas fields. They can be trimmed to conform with NACE MR0175/ISO 15156.
The WKM DynaSeal 310 seat is protected in a machined recess or deep pocket that surrounds and protects the seat. This design eliminates cold flow into the valve conduit and avoids potential seat damage from ball movement or flow media.
Trim 42 Seats
Seats are manufactured of filled TFE and rated to 1500 psi MOP. With working temperatures to 500° F (260° C) and low-torque operation, these seats satisfy even the most difficult of processing requirements.
Trim 43 Seats
Seats are manufactured of acetal plastic and are rated to 3000 psi MOP and working temperatures to 220° F (104° C). These seats are designed to handle the most demanding applications. They can flex under pressure and provide a consistent range of low-torque operations. They also provide a full face seal against the ball and multiple seals against the top and back of the pocket to provide a positive seal.
