This is an In-Line poppet type check valve, allowing flow to pass through a pipe line only in one direction. When flow reverses, the poppet will close and prevent flow in the opposite direction. Observe the maximum working pressure listed for each model. Select seat materials from pricing pages.

This valve is normally used for liquids, air, or gases Use only clean filtered or strained liquids or gases. To make sure the valves are protected from dirt and debris which might clog the valve, a strainer with a fine wire mesh should be installed before the inlet of the valve. In-line strainer fittings or basket strainers can be purchased from Straval to solve this problem. The valve can also be used for vacuum relief service where the vacuum is connected to the discharge port. Please contact Factory for technical assistance!

Scroll down below to click on a valve size for pricing and then click on the spring range to see which options are available for that size. After selecting your options you may then print out a price, e-mail it (without having to contact the factory), and then when you are ready, proceed to order.
When ordering don't forget to state your desired crack set pressure if you expect the valve to open at some other pressure than the default setting. There is no extra charge for this. If the set pressure is not specified, the valve will be set at 1.5 psig (0.10 barg)

Body: Standard materials are 303SS & 316 Stainless Steel
Piston: 303SS & 316 Stainless Steel
Spring: 303SS & 316 Stainless Steel
Lock nut: 303SS & 316 Stainless Steel
Elastomeric seal: Bubble-tight seal is achieved with soft elastomers such as Buna, Viton, and EPDM and Kalrez, to a lesser degree with the harder seal material, Teflon (PTFE) .
Tamper-proof construction-This valve is not externally adjustable & requires removal of the valve to change the pressure setting after the system is depressurized.
Adjustable pressure-setting valve can be factory-set or adjusted in the field. Standard set pressure is 1.5 psig (0.10 barg), but can be customized

This is a poppet (piston) and spring type check valve where the spring constantly opposes the pressure acting against the piston which seals off the inlet port. The desired cracking or opening pressure is achieved by compressing the spring until the spring force is adequate to balance the pressure force acting against the poppet. Although the valve is set for a specific cracking pressure at the factory, it can be adjusted in the field by removing the valve from the piping system. It is not externally adjustable. Setting the correct cracking pressure in the field may require several tries, and requires measurement with a pressure gauge to verify. In order to make the pressure adjustment, the valve needs to be unscrewed from its mounting position with pressure removed from the line. Increasing the spring pressure increases the crack pressure and vice versa. A small nut driver, screwdriver or needle nose pliers may be used to make pressure adjustments for low the pressure settings these valves are usually set to. However, ordering the valve to the correct cracking pressure would minimize or eliminate the need for making pressure adjustments in the field.
