Check Valve V-030

A check valve is a type of valve that allows fluid to flow in one direction and automatically prevents backflow. Commonly referred to as a non-return valve or one-way check valve, the V-030 protects pumps and process lines from reverse flow and water hammer in industrial systems. It features a simple structure, sensitive operation, no manual intervention required, and low maintenance costs.

Check Valve V-030

A check valve is a one-way valve that relies on the flow pressure of the medium itself to open and close. Its primary function is to prevent the reverse flow of fluid in pipeline systems, thereby safeguarding the stable operation of equipment and systems. It automatically opens under the forward fluid pressure through its internal disc, ball, or diaphragm. When the medium flows in the opposite direction or the pressure drops, the valve disc automatically closes under the force of gravity or the spring force, thereby preventing reverse flow of the medium.

Check valves are widely used in oil & gas, petrochemical, water supply and drainage, HVAC, marine, and food & beverage industries. Typical installations include pump outlets, air compressor pipelines, boiler systems, and chemical process lines. The V-030 is available in stainless steel check valve and carbon steel check valve variants to match chemical compatibility and strength needs. It has a working pressure range up to 600 psi (PN40) and a temperature of -20°C to 200°C (for PTFE sealing) and up to 400°C (for metal sealing). You can use the V-030 as a pump check valve, suction non-return valve, or backflow prevention valve.

특징

Unidirectional Flow Design (non-return valve)

The check valve ensures fluid flows in only one direction through its internal valve disc structure, effectively preventing backflow and backpressure in pump discharge lines and pipeline systems.

Low Maintenance Costs

This product has a simple structure with few components, resulting in low maintenance frequency and costs for plant operators and maintenance teams.

Flexible Installation

Supports horizontal or vertical installation and offers multiple connection options such as threaded, flanged, or welded connections to suit process piping and HVAC installs.

고압 저항성

The valve body has a robust structure and can withstand high working pressures, making it suitable for harsh environments such as petrochemical and marine shipping applications.

응용 프로그램

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.

선박

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.

설치 가이드

Install the Check Valve V-030 downstream of the pump or in the intended line. First, isolate and fully depressurize the pipeline. Check the valve size, material, and thread standard (NPT or G). Align the valve so the flow arrow matches system flow and support adjacent piping to avoid body loads. For threaded connections, use approved thread sealant or a light wrap of PTFE tape and hand-start threads to prevent cross-threading. For flanged installations, use 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. Fit an upstream strainer to protect the check valve. Slowly pressurize, cycle the valve, then perform leak and differential-pressure checks.

자주 묻는 질문

Looking for answers about Check Valves? 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.
