Stainless Steel Sanitary Check Valve in Tri-Clamp, AISI 316 L with Viton Seat
PRODUCT INTRODUCTION
1. Description our Sanitary Check Valves
Sanitary check valves also known as one-way valves, their roles are to prevent the pipeline water back in the media. They are specifically used for the food handling and processing industries to prevent backflow of product. Commonly used with liquid products, spring check valves are designed to assist closure pressure to create a positive shutoff.
Sanitary check valves 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.
2. Advantage of Sanitary Check Valve
Sanitary check valve has many advantages such as removable connection, simple structure, and easy maintenance;
Sanitary check valves are high-quality pieces to ensure the use performance and service life;
Adamant valves can provide valve body and disc materials such as AISI 304 or AISI 316L, 304L and 316 materials, automated or manual operation valve according to your requests.
Applicable medium: water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea and so on,
Connection: flange, butt welding, thread, socket welding.

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.
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:
