(8)This spring check valve is machined and polished to 3A standards. The clamp assembly design allows quick and easy maintenance and has a special angled plunger design to prevent even low pressure leak-through.
Features:
Maximum operating pressure: 145 PSI
Operating temperature range of 15ºF to 200ºF
Full size flow plate with a long bushing helps minimize stem wear
(4)When liquid flows through the valve, the ball is forced into the branch of the valve allowing full fluid flow. When the liquid stops, equalizing the pressure, the ball drops back into the seat, preventing backflow. Should reverse flow occur, the differential pressure will cause the ball to seal firmly against the seat preventing leakage.
Features:
Maximum operating pressure: 250 PSI
Maximum operating temperature: 250ºF
Two piece construction for easier alignment during installation
Various end configurations available: clamp, weld, I-line, Q-line, bevel seat and John Perry
Polished ID and OD to 3A standards
All metal contact surfaces of 316L stainless steel construction
Air blow check valve can be added (see air blow for sizing)
(15)The air blow check valve is designed to pressurize lines with air to clean out product or cleaning solutions. It is fail-safe because the simple air-to-open, spring-to-close mechanism prevents backflow. Can be used with a ball check valve. The valves are available with three different end configurations to allow quick assembly and disassembly when replacing filter media, cleaning or inspecting. Conforms to 3A accepted practice 604-05 for supplying air under pressure in contact with milk products and product contact surfaces with optional filter disc.
Repair Kit contains: (1) EPDM / 316L stainless perforated disc (1) 304 stainless spring retainer (1) 304 stainless spring (1) Nylon stem guide (1) EPDM / 316L stem and plug
