Which is better swing or spring check valve?

A spring loaded check valve will help minimize effects of water hammer, while a swing check valve can exacerbate the issue. Any water hammering effects present in a piping system can potentially be amplified by a swing check valve.

Can a spring loaded check valve be used as a pressure relief valve?

Inline spring-loaded check valves can be used in low pressure relief applications. The key to pressure relief in this case is that the poppet moves away from the valve seat when the force of the upstream pressure exerts a greater force than that of the spring, allowing the media to pass through the outlet port.

What is a spring loaded valve?

Spring loaded PSV model A spring loaded pressure safety valve is a conventional pressure relief valve which is designed to open at a predetermined pressure and protect a vessel or system from excess pressure by removing or relieving fluid from that vessel or system.

What kind of fittings do I need for Spring Check valves?

Insert tubing into the fitting— no heat, solder, or flux required. Two sleeves give the fittings extra gripping power. They bite into tubing as you tighten the nut to form a strong seal. All are compatible with Swagelok®, Let- Lok, and Parker A-Lok fittings. For more durability than plastic, these valves have a metal body.
