Midwest Control H-300-502M-1311 3" Check Valve Carbon, 200 PSI

Check valves are an essential part of industrial equipment for air and water applications. With few moving parts to ar out, these valves withstand the frequent opening and closing of pulsating flow and rapid flow reversal. They open to allow flow in one direction and close when flow stops or reverses. Without the use of a check valve most mechanical equipment would be damaged when the pressure drops or the system shuts off and the flow is reversed.

Features:

• Flexi-Hinge Design Check Valves have a Unique Post Design Contour which Conforms to the Closure Angle of the Valve Plates, Providing a Positive, Quick Seal with Low Back Pressure
• Cracking Pressure: 0.1 PSID, Fully Open: 0.5 PSID
• Construction: Carbon Steel Body, Aluminum Internals Buna N Seals and Stainless Steel Spring (for Low Flow or Vertically Piped Applications with a Downward Flow )
• Maximum Temperature: 225 F
• Maximum Operating Pressure: 200 PSI
• Rated for 29"; Hg
• Male NPT Connections
