The KX Module
The Heart of the Piston Valve
The valve rings (KX-GT) are made of specially treated graphite. They have no asbestos-containing materials and make the valve maintenance-free. Simply “install and forget”. The coupling pressure on the piston is so high that media are reliably checked to 900 PSI in any aggregate condition and at temperatures ranging from -50º F to +800º F. The various expansion coefficients of the valve components which arise during alternating thermal loads are fully compensated by the valve rings. They are reliably tight in all operating states.
The bonnet (1) presses against the sealing element. The two rings (2) and (3) are pre-sealed and increase their coupling pressure on the casing and piston.
