Introducing the Eagle's 1/2" Stainless Steel Sanitary One Way Check Valve - the perfect solution for home kitchens, brewing setups, and water systems with backflow. This valve stops reverse flow immediately, is simple to keep clean, and offers commercial-grade reliability for home projects.

Product Overview

The Eagle 1/2" sanitary check valve is a one-way flow control device made of solid 316L stainless steel and equipped with a spring. With liquid flowing in, the disc assembly is pushed off its seat, permitting fluid to flow without restriction. Once the flow stops or turns back, the valve disc is pushed by the spring back to its seat. The inner surface of the valve body has smooth, 32Ra electropolished surface finish, making it difficult for bacteria and residue to stick to the surface of the valve. It is connected through a butt-weld, making the connection permanent and good for applications with pressures of up to 145 psi and temperatures of up to 200°F. This valve is 1/2 inches, which fits in with tube diameter used in home brewing, espresso machines, reverse osmosis, and small food production.

Frequently Asked Questions

What is a sanitary check valve?

The sanitary check valves are basically one-way flow devices constructed particularly for hygienic use or in hygienic applications. The valve allows free flow of the liquid in the forward direction and closes as soon as the flow stops or gets reversed, thereby preventing the backflow. Unlike in conventional check valves used in plumbing, sanitary check valve is made from 316L steel with electropolished interior surface finish so as to ensure bacterial resistance and perfect cleaning, which is very essential in food, beverages and brewing applications where product purity is of utmost importance.

What is the difference between a one-way check valve and a backflow preventer?

The one-way valve makes use of a spring-loaded disc or a ball to obtain flows in just one direction. It is a straightforward device that doesn't come with any test ports or plans in place. A backflow preventer is much more intricate since it consists of a double check valve and two separate check mechanism along with a relief valve. Plumbing codes require backflow preventers to be installed in plumbing systems once there is a separation between water supply and other sources of possible contamination. A check valve on its own does not satisfy plumbing codes in terms of backflow prevention.

What are the common problems with check valves?

The most frequently encountered issues with check valves include seat leakage (the valve does not fully seal when closed, usually due to improper sealing caused by particles on the seat or deterioration of the elastomer seal), sticking (the disc or ball does not work properly to open and close, due to accumulation of deposits or corrosion in lower-grade valves), and installation orientation mistakes (if a swing check valve is installed in a vertical down-flow conduit, it will never shut down). Eagle's sanitary check valves provide solutions for these problems by using a special 316L stainless steel material capable of withstanding corrosion, a special electropolished finish to prevent product adhesion from occurring, and a spring-loaded construction that functions at any orientation.

Are a check valve and one-way valve the same?

Yes. The one-way valve and the check valve are actually identical in terms of functionality. Both terms refer to a type of valve that only permits fluid to flow in one direction and prevents back flow automatically. In the processing sector, the technical term used often is ‘check valve’ while ‘one-way valve’ is more common in the hobbyist and consumer industry. This Eagle valve is both because it is a high precision check valve designed at 3-A sanitary standards so it may be used in private kitchens and brewing workshops.
