What is the difference between trunnion and floating ball valve?

The ball in a trunnion ball valve is supported by the stem and trunnion, reducing the operating torque, while the seats are spring loaded. In a floating ball valve, the ball floats and the seats are fixed while the ball is only supported by the stem.

What is meant by floating ball valve?

Floating ball valves are the most common type of valve used in industrial piping systems. These valves are designed so that as the seats begin to wear the pressure from the media flowing through the valve will force the ball against the downstream seat to maintain a tight seal.

What is trunnion mounted ball valve?

A trunnion mounted valve means that the ball is con- strained by bearings and is only allowed to rotate, the majority of the hydraulic load is supported by the Sy- stem constraints, resulting in low bearing pressure and no shaft fatigue.

What is a WKM valve?

The Cameron WKM high-performance butterfly valve offers the high performance of ball and gate valves with the low-cost, lightweight benefits of a butterfly valve design. It is ideal for handling water, oil, steam, gas, and slurries.

What is trunnion mount?

A Trunnion mount shock mounts the shock body directly to the linkage – there are two threaded holes on the shock body and linkage bolts thread directly into them. A Trunnion mount shortens the overall eye-to-eye length of the shock while allowing it to have the same amount or more, of shock stroke.

What is a trunnion seal?

Chesterton’s Kaplan Turbine Runner Blade Trunnion Split Seal has a pin and lock design that keeps the turbine motion from pulling the split seal apart and also uses load pressure to join cut ends.

Is trunnion mount better?

A Trunnion mount shortens the overall eye-to-eye length of the shock while allowing it to have the same amount or more, of shock stroke. This can be advantageous to frame designers.

Are all trunnion mounts the same?

That is the current standard yes, but for 2022 product they are going to increase it to 54.99mm spacing to ensure people buy new product.

What kind of valves does WKM make?

The WKM product line offers a broad line of valves including ANSI gate valves, DynaSeal ball valves and DynaCentric butterfly valves, all built to standards for demanding applications. The WKM® model 210A ball valve is a two piece design with ductile iron body and tailpiece.

What is the maximum pressure rating for a floating ball valve?

Maximum pressure ratings are 2000 psi, 1″ to 3″x2″ valves, and 1500 psi for the 3″x3″ and 4″x3″ valves. This valve is primarily used in the Oilfield market, typically chosen for the following applications: WKM® DynaSeal Model 310C 2-piece floating ball valves satisfy a wide range of applications.

What is a 370d6 ball valve?

Cameron’s WKM 370D6 trunnion mounted ball valves are designed and engineered for heavy-duty performance. Used in many general purpose petroleum and chemical process applications, these valves also can be specified for more demanding applications.

How much pressure does a 210a ball valve have?

The WKM® model 210A ball valve is a two piece design with ductile iron body and tailpiece. This economical valve includes many of the premium design features found in the WKM carbon steel 310C and 310D ball valves. It is available in 1″ to 4″x3″ sizes. Working pressures offered are 1,000, 1,500 and 2,000 psi.
