Stainless Steel Sanitary Check Valves 3/4" Long Stem Bushing

Product Specification

3/4" AISI 316L Stainless Steel Check Valve With Two Splitted Design

Stainless sanitary ball check valves are designed to allow full product flow during processing. Once the product flow stops the ball rolls back to the seat at inlet preventing backflow. Stainless steel sanitary ball check valves are commonly used with liquid products. Sanitary ball check valves are available standard in clamp or weld ends, but others are available per request. Sanitary ball check valve replacement parts are available upon request. Buna gaskets are standard, but Viton gaskets are available upon request.

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).

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.

Design:

• Forged valve body ensures non-porous, smooth surfaces and stable structure.
• Compact and simple structure makes sanitary check valve easy to clean and maintain without special tools.
• Sanitary weld check valve Male check valve and Sanitary Tri Clamp Check Valve are two splitted design, assembled by a clamp and sealed with a gasket.
• Sanitary union type check valve is basically consist of a valve body, a cover and a nuts in threaded union form.
• Ribbed construction of the stainless steel disc resists heavy pressure hammer, minimizes the resistance to flow and also serves as a guide to the valve plug.
• Eccentric design allows the check valve installing vertically or horizontally.

Features:

• various end connections available
• sizes from ½" thru 4"
• operating temperature range: 15°F to 200°F
• maximum operating pressure: 145 PSI
• 3A authorized 58-00
• full size flow plate
• long stem bushing for increased cycle life
• suitable for low and medium viscosity fluids
• field serviceable (no special tools required)

Are different to many other types of valves,for check valves work automatically and most are not controlled by a person or any external control. Accordingly, most do not have any valve handle or stem. Thus there is an important concept in check valves, it is, the cracking pressure. Cracking pressure is the minimum upstream pressure at which the valve will operate. So the check valve is designed for and can therefore be specified for a specific cracking pressure.
