Gemco P21 High Performance Spherical Disc Valve

SPECIFICATION GUIDE

SPHERICAL DISC VALVES

TYPE: P21 HIGH PERFORMANCE

The P21 High Performance Spherical Disc Valve is designed to meet tomorrow's demanding requirements for containment of solids, powders and slurries. Engineered for pressure assisted sealing from full vacuum to 150 PSI. GEMCO valves use a spherical disc which moves

across the seat wiping material away from the sealing area. This self wiping action eliminates pinch points - the source of most valve wear. The P21 is offered with standard ANSI or DIN flanges and ISO actuator mounting.
