Parker provides the industry's widest selection of check valves, available in a variety of end connections. Our valves are used in a diverse range of applications, from air and fuel systems to load holding. Our check valves utilize a variety of media including oil, air, and water and are made from materials such as aluminum, stainless steel, brass, and carbon steel. Parker check

Description: , this in-line check valve has a low 0.0.087 psi cracking pressure and is ideal for infusion, drainage and irrigation applications. Qosina offers a variety of flow rates, materials, cracking pressure and back pressure options. Check. Pressure Rating: 0.0870 psi.

Clean Room Pressure-RegulatingValves for Water, Air, and Inert Gas. To maintain contaminant-free standards in clean room environments, these valves come cleaned and bagged to Fed. Std. Class 100 and ISO Class 5 clean room standards and have a 316 stainless steel body with a smooth finish to resist dust collection.

Check valves are traditionally designed as a simple poppet/spring system where the spring is designed to equal the force created from the sealing area of the valve seat multiplied by the cracking pressure. Since the valve seat diameter in these types of valves are relatively small, less than 0.5 inches diameter, a low cracking pressure required

Our Full Port Check Valves provide more flow and lower pressure drops than conventional check valves. Our elastomer hinge check valve design takes 

Low Pressure Check Valves. Low pressure check valves are check valves used for low pressure applications. It include spring check valve, swing check valve, and wafer check valve. It allow fluids to flow in one direction only and prevent back-flow of fluids. Low pressure check valves are available in stainless steel material.

Ball check valve. Video Credit: iecSimulations / CC BY 3.0. Advantages: Can be used with steam, air, gas, water, and vapor lines with high flow velocities, can be installed in lines with vertical flow, available with renewable seat rings. A double-disc or wafer check valve consists of two half-circle disks hinged together. The two disks fold together upon positive flow and retract to a full

If the upstream pressure falls below the cracking pressure or there is back pressure (flow attempting to move from the outlet to the inlet), the check valve 

High-quality gas non-return valves protect against dangerous gas backflow. Low opening pressure - leak-tight elastomere sealing system - long service life.

Check valves are one-way or nonreturn valves that open with fluid movement and pressure, and close to prevent backflow of the pressure to upstream equipment 

The S&J 97220 Back Pressure Check Valve uses a free swinging “pendulum” pallet design to provide maximum flow rates with a minimum pressure drop in low
