Reliable Valve-Seat Operation
Critical service valves depend on soft-seating materials to adequately perform at pressures higher than 600 psi and temperatures above 250ºF. The seats must maintain a seal when pressurized and depressurized at room temperature, as well as when at temperatures higher than 250ºF.
A critical valve must be cycled several hundreds of times at pressure and at elevated temperature. Commonly used seat polymers such as acetal, nylon, and PEEK generate high torques when the valves are cycled under pressure at elevated temperature. This elevated torque condition can be greatly reduced or eliminated when using as a seating material such as POKETONE-aliphatic polyketone-polymer. The inherent low coefficient of friction, low moisture absorption, and self-lubricating characteristics of POKETONE makes this polymer ideal for valve seating material.
In a recent test, an ANSI 600 class ball valve equipped with POKETONE seats demonstrated a very low torque increase when switching the valve hundreds of times. Torque increase at 1,500 psi at 250ºF was only 33%. The same valve equipped with Acetal POM seats showed a torque increase in excess of 300%. POKETONE-aliphatic-polyketone should be considered the material of choice for critical service valves when seal reliability is key to valve performance. POKETONE truly generates peace of mind in valve operation.
