Valves and Filters

A check valve is a type of valve that allows fluid to flow in one direction and automatically prevents backflow. The V-030 check valve (also known as a non-return valve or one-way check valve) effectively protects pumps and process pipelines in industrial systems from backflow and water hammer effects. This valve features a simple structure and responsive operation, requiring no manual intervention and offering low maintenance costs.

Check Valve V-030

A check valve is a one-way valve that opens and closes based on the flow pressure of the medium itself. Its primary function is to prevent backflow of fluid in piping systems, thereby ensuring the stable operation of equipment and systems. When fluid flows in the forward direction, the valve disc, ball, or diaphragm inside the valve automatically opens under the pressure of the fluid. When the medium flows in reverse or pressure drops, the valve disc closes automatically under the force of gravity or a spring, thereby preventing backflow.

Check valves are widely used in oil and gas, petrochemical, water supply and drainage, HVAC, marine, and food and beverage industries. Typical installation locations include pump outlets, air compressor pipelines, boiler systems, and chemical process lines. The V-030 series offers both stainless steel and carbon steel check valve models to meet varying chemical compatibility and strength requirements. Operating pressure ranges up to 600 psi (PN40), with temperature ratings from -20°C to 200°C (PTFE seal) and up to 400°C (metal seal). The V-030 can function as a pump check valve, suction check valve, or back pressure prevention valve.

Features

Unidirectional Flow Design (Check Valve)

This check valve ensures one-way fluid flow through its internal disc structure, effectively preventing backflow and back pressure in pump discharge lines and piping systems.

Low Maintenance Cost

Featuring a simple structure and minimal components, this product significantly reduces maintenance frequency and costs for plant operators and maintenance teams.

Flexible Installation (Threaded/Flanged/Clamp)

Supports horizontal or vertical mounting with multiple connection options including threaded, flanged, or welded interfaces, accommodating process piping and HVAC system installation requirements.

High-Pressure Tolerance

The robust valve body construction withstands elevated operating pressures, making it suitable for demanding environments such as petrochemical plants and marine transportation.

Applications

Oil & Gas

Check Valves are widely used in the petrochemical industries, where robust stainless steel bodies resist corrosive media and prevent costly backflow events. They protect pump discharge lines and ensure safe skid operation.

Food & Beverage

In food and beverage plants, sanitary and corrosion-resistant options prevent contamination and maintain product quality while ensuring hygienic backflow protection.

Pharmaceutical & Labs

The pharmaceutical sector relies on precise, leak-free check valves to protect dosing pumps and sterile processes from reverse contamination.

Marine

In marine and shipbuilding, durable check valves prevent reverse flow in ballast, bilge, and fuel systems, with models designed to handle saltwater and cyclic loads.

More About Us

Installation Guide

Install check valve V-030 downstream of the pump or in the designated pipeline. First isolate the pipeline and fully relieve pressure. Verify valve specifications, material, and thread standard (NPT or G). Align the valve so the flow arrow matches the system flow direction, and support adjacent piping to prevent stress on the valve body. For threaded connections, use certified thread sealant or wrap a thin layer of PTFE tape, then hand-tighten threads to prevent stripping. For flange installation, select the correct gasket and tighten bolts in a star pattern to the specified torque. If welding is required, follow certified welding procedures and allow the valve to cool. Install a filter upstream to protect the check valve. Slowly pressurize and cycle the valve, then perform leak and differential pressure testing.

FAQs

Looking for answers about Check Valve? Visit our FAQ section for detailed information and expert insights.

Can Check Valves be used for flow regulation?

No, their primary function is to prevent backflow, not to control flow.

What types of check valves are there?

Common types of check valves include swing-type, lift-type, ball-type, and double-disc-type.

How do you determine the installation direction?

The valve body of a check valve typically has an arrow indicating the flow direction; the direction the arrow points is the correct direction for medium flow.

Can a check valve be installed at the pump outlet?

Yes, the pump outlet is one of the common installation locations, helping to prevent backflow from damaging the pump.

Can it get stuck?

It may get stuck if left unused for an extended period or if there are impurities inside. It is recommended to install a filter and perform regular inspections.
