Check Valve
Check valves are hydraulic valves that allow fluid or gas to flow in one direction only, preventing backflow or reverse flow in a piping system. These valves automatically open and close based on the pressure difference between the inlet and outlet sides of the valve.
• Simple and compact design
• Low pressure drop
• Easy to install and maintain
• Durable and reliable
• Available in a range of sizes, materials, and end connections
Pressure control check valves can be found in every pneumatic and hydraulic system. They assist in a variety of functions, from maintaining system pressure below desired limits, to maintaining set pressure levels in partial circuits. Different types of pressure control check valves include relief valves, pressure reducing valves, sequence valves, balance valves, safety valves and unloading valves.
• Pressure Relief Valve: Limits the maximum pressure in the system by diverting excess gas when the pressure is too high.
• Sequence Valves: Sequence valves are normally closed two-way valves that regulate the order in which various functions in the circuit occur.
• Pressure Reducing Valve: A pressure relief valve is usually a two-way valve that opens and closes when sufficient downstream pressure is applied.
• Balance valve: To balance weight, used to maintain set pressure in one part of the circuit.
Check valves can be used in various applications where backflow prevention is critical. In plumbing systems, they are commonly used to prevent contaminated water from flowing back into the clean water supply. In the oil and gas industry, hydraulic control check valves can prevent the reverse flow of fluid or gas, which could cause equipment damage or safety hazards. In chemical processing, hydraulic pressure control check valves can prevent the mixing of different chemicals and avoid cross-contamination. Mainly include:
• Plumbing systems
• Oil and gas industry
• Chemical processing
• Water treatment
• HVAC systems
• Power generation
Hydraulic flow control check valves are also used in HVAC systems to prevent the backflow of air and in power generation to prevent the backflow of steam or water, which could cause damage to turbines. They are available in different materials such as brass, stainless steel, and PVC, making them suitable for a wide range of fluids and gases.

How do hydraulic check valves work?
Check valves can be used as directional or pressure control in hydraulic systems. Hydraulic check valves have two ports, an inlet port and an outlet port, and they are flow sensitive and rely on fluid to open and close the internal valve seat. Hydraulic check valves are unique in that they are one of the only valve types that do not require any human intervention to operate. Hydraulic check valves are fully automatic.
What are the most common applications of check valves in hydraulic systems?
Connect to the system pump, one port of the cylinder, and the system line to the reservoir.
Where should the check valve be installed?
Check valves can be installed on horizontal or vertical pipes with flow upwards.
