Sanitary Check Valve with Tri-clamp Ends

Sanitary Check Valve with Tri-clamp Ends

Application

Sanitary check valve, also known as "non-return valve", is designed for use in process piping installations to prevent reverse flow. AV-3C series is a spring check valve with tri-clamp ends.

 

Specification:

Sizes are available from 1/2" to 4" (1/2", 3/4", 1”, 1 1/2", 2", 2 1/2", 3", 4")

DN15 to DN100 (DN15, DN20, DN25, DN40, DN50, DN65, DN80, DN100)

Valve body can be AISI 304 or AISI 316L.

Valve seat: EPDM, VMQ (silicone), Viton (FPM) for choose from, all complying with FDA 21CFR177.2600.

End connection can be butt-welded, sanitary clamp, threaded or others upon request.

Max. working pressure: 145psi (10bar)

Opening pressure: 4.5psi/0.3 bar (DN25/1"), 3 psi/0.2 bar (DN32/0.75" to DN40/1.5"), 1.5 psi/0.1 bar (DN50/2" to DN100/4")

Working temperature range: 14 ~ 248°F (-10 ~ 120°C) with EPDM seat.

Surface treatment: Ra 32μin (0.8μm) as default, others available upon request.

 

Working Principle
A check valve opens when the pressure below the valve plug exceeds the pressure above the valve plug and the spring force. The valve close when pressure equalization has been achieved. The below picture shows the right installation:
