Balanced Piston Valves
Balanced Piston Valve
A balanced piston valve is a piston valve with a design that balances the pressure acting above and below the piston. Through pressure balancing, the valve can be opened and closed with low effort even in large sizes and high pressures; graphite rings provide sealing without gland leakage.
Supplied with GGG40.3 ductile iron body and stainless steel reinforced pure graphite rings between DN65 and DN200, in pressure classes PN16 and PN40, as EN 1092-2 flanged and gear operated (gear box).
