Valves
Asahi/America thermoplastic gate valves
Asahi/America’s thermoplastic gate valves are designed for large-diameter, full-port applications where reliable on/off control is required. When fully open, the valves offer a straight-through flow path roughly equal to the inner diameter of the connected pipe minimizing pressure drop. They operate when the hand wheel and stem screw (or electric actuator) move a cylindrical plug, the gate, up and down at right angles to the fluid flow. Their sliding plug design provides a larger seating area than conventional gate valves so they can be used for throttling. This significantly larger seating area, which runs 360 degrees around the cylindrical plug, has also virtually eliminated the valve chatter normally associated with gate valves. The plug is made of solid polypropylene, and the valves use a nonrising stem for compact, durable operation. They are fully vacuum rated and have no metal-to-media contact, which helps reduce corrosion-related failures and maintenance. 800-343-3618; www.asahi-america.com
DeZURIK APCO CVS-6000D Swing Check Valve
