    Pressure Relief Valve Is Necessary For Positive Displacement Pump

    A pressure relief valve is a critical piece of equipment for positive displacement pumps. In short, it’s a valve that helps prevent the buildup of pressure in the pump, which can damage it and cause it to fail. If you are using a positive displacement pump in any capacity, it is essential that you install a pressure relief valve. Failure to do so can result in serious injury or even death. So what exactly does a pressure relief valve do? Here are four key ways it can help you stay safe: 1) It Prevents Pump Damage: When the pressure inside the pump gets too high, the relief valve opens and allows air to enter the pump. This dilutes the pressure and prevents the pump from overloading. 2) It Prevents Pump Failure: If the pressure inside the pump becomes too high, the relief valve can also break, causing the pump to stop working. 3) It Helps Keep Equipment Running Smoothly: When there’s a lot of pressure inside the pump, it can cause parts to wear out quickly. That’s where a relief valve comes in handy—it keeps the equipment running smoothly by releasing some of that pressure when needed. 4) It Prevents In

    What is a Pressure Relief Valve?

    A pressure relief valve is a safety device that allows the flow of gas or liquid when the pressure inside the system becomes too high. It is usually found on systems that use positive displacement pumps, such as oil wells.

    How Does a Pressure Relief Valve Work?

    A pressure relief valve is a safety device that helps prevent overpressurization of a system. It does this by releasing pressure when the system reaches a preset pressure, preventing an explosion or uncontrolled release of gas or steam.

    The typical pressure relief valve has three parts: the body, the stem, and the spring. When the valve is closed, the body creates a seal against the fluid being pumped. This pressure causes the stem to push up on a spring, which opens the valve. The spring ensures that the valve will reopen quickly in case of an overpressure situation.

    When Do You Need a Pressure Relief Valve?

    A pressure relief valve is a must-have for any positive displacement pump system. When the system is initially installed, the builder must verify that the pump has been properly designed and fitted with the appropriate type of pressure relief valve. Generally speaking, there are two types of pressure relief valves: those with automatic shutoff and those without automatic shutoff.

    Automatic shutoff valves prevent the system from running until pre-determined pressures are reached, usually around 100 PSI. This prevents overpressurization and potential damage to the pump or system. Without automatic shutoff, an operator must constantly monitor the pressure in order to maintain safe operation.


    A pressure relief valve is a key part of any positive displacement pump, as it allows the system to handle high pressures without bursting. If your pressure relief valve is not functioning properly, your positive displacement pump may fail and cause serious damage. By checking for and fixing any issues with your pressure relief valves, you can ensure that your positive displacement pump works as it should and keeps you and your property safe.
