Pressure Relief Valve V-035

A Pressure Relief Valve is a safety device designed to protect pipeline systems and equipment from damage caused by high pressure, effectively preventing explosions, leaks, or other safety incidents. This spring-loaded safety valve acts by releasing excess pressure, hence preventing overpressure incidents in liquid and gas systems.

Pressure Relief Valve V-035

The Pressure Relief Valve V-035 is an indispensable safety device in pressure systems, with its core function being to prevent safety risks caused by excessive internal system pressure. When the internal system pressure exceeds the preset limit, the safety relief valve automatically opens to release excess pressure medium to a safe discharge path, thereby preventing accidents. This type of valve serves as the final line of defense in various pressure systems and is a core component for ensuring safe operation. It is not only suitable for liquid systems but is also widely used in pressure control for gases, steam, and other media, with extensive applications in industries such as petrochemicals, hydraulic systems, and food processing, among other fields.

These valves have a working pressure range of up to 600 psi (PN40). The temperature range is -20°C to 200°C (for PTFE sealing) and up to 400°C with metal sealing. With excellent pressure resistance, rapid response speed, superior sealing performance, and extended service life, the Pressure Relief Valve maintains stable and reliable performance even under complex operating conditions.

Caractéristiques

Automatic Pressure Relief

When system pressure exceeds the set value, the valve automatically opens to release excess pressure, preventing equipment damage or personal injury. As an automatic pressure relief valve, it provides immediate overpressure protection for pipelines, vessels, and pressure vessels.

High-Pressure Resistance

Constructed from high-strength stainless steel, brass, or aluminum alloy, it offers excellent high-pressure resistance and is suitable for high-pressure systems. This high-pressure relief valve is suitable for hydraulic and industrial systems that require robust material strength.

High Response Speed

Featuring a calibrated, high-sensitivity spring design, it responds instantly when pressure exceeds the limit, ensuring timely pressure relief protection. The fast-acting safety valve limits peak pressure spikes and reduces the risk of equipment damage during transient events.

Precise Setting

The valve opening pressure can be precisely adjusted according to system requirements, ensuring that the pressure relief action is triggered within a safe range to prevent bad operation. The adjustable pressure relief valve ensures reliable activation within tight safety margins, thereby reducing the chances of mistakes due to false trips.

Applications

Pétrochimie

The pressure relief valve can be installed on process columns, separators, and storage vessels to prevent overpressure during upset conditions. Corrosion-resistant options and certified set-pressure testing ensure safe operation in aggressive hydrocarbon environments.

Hydraulic Systems

To limit system pressure spikes, a safety relief valve can be used on pump discharge lines and hydraulic accumulators. Fast response reduces risk to pumps, seals, and downstream piping during sudden load changes.

Power Generation & Boilers

A high-pressure relief valve protects boilers, heat exchangers, and pressure vessels from dangerous overpressure. Reliable opening and re-seating help maintain plant safety and reduce forced outages.

Food, Beverage & Pharmaceutical

Sanitary or stainless steel adjustable pressure relief valves can be applied to protect pressurized process vessels and sanitary tanks. Precise set-pressure control prevents contamination events while meeting regulatory safety requirements.

Guide d'installation

Select a relief discharge location that vents to a safe area or piping system. Isolate and depressurize the line before starting work. Fit the safety relief valve vertically where possible, with the outlet clear of obstructions. Use proper thread sealant and hand-start threads to avoid cross-threading; torque to recommended values. Install a discharge collector or pipe sized to handle relief flow and slope it away from personnel areas. Keep the adjustment screw accessible but protected. For steam or hot fluids, include cooling and drainage measures. After installation, set the relief pressure, perform a controlled lift test, then check for leaks and proper reseating. Record set pressure and test results for safety compliance.

FAQ

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

What’s the difference between a Relief Valve and a Safety Valve?

Both prevent overpressure, but Safety Valves are mainly for steam/gas with quick full-opening, while Relief Valves are used for both liquid and gas and can provide more gradual pressure relief.

How often does maintenance need to be performed?

Depending on usage frequency and operating conditions, we generally recommend inspection every 6–12 months. If any functional issues are detected, timely maintenance or replacement should be conducted.

Can frequent tripping occur?

If the set pressure is too low or there are significant fluctuations in system pressure, this may occur. Adjustments should be made promptly.
