mud pump pressure relief valve made in china

Since 2006, Envirovalve has been changing the game for safety relief valves. Our innovative designs for pressure relief valves have already made significant impacts on the industries we service. The most impactful of those designs has been our Accu-Shear Pin Device.

Our ASME certified Accu-Shear pressure relief devices have a revolutionary design that is different from other traditional Buckling Pin Devices and Valves like Rupture Pin, Buckling Pin, Rupture Disc and BPRV. The device does what its name implies; it shears or breaks the pin as opposed to compressing or bending the pin that you see in most pressure relief valves.

The Accu-Shear device opens and closes like a butterfly valve, and the pin is situated on the outside of the device which allows for easy and efficient replacement. The Accu-Shear pin is designed to break cleanly every time. During the manufacture process, every fifth pin is broken to insure the material or tolerance has not changed. Our Accu-Shear pins are less costly than our competitor’s pins and are easily replaced without needing to tear down the entire system.

Pinch valves control the flow of fluids (liquid, gas or power) and provide a leak-proof seal when closed. They are cost-effective, simple to install and require little maintenance.

The valves are made up of a valve body and a cylindrical sleeve reinforced with natural or synthetic rubber. Typically in an open state, the valve is closed by the application of pressure between the valve body and the sleeve. This pressure is created by a fluid, usually compressed air,that crushes the sleeve in a particular direction, completely closing the valve.

Available in cast iron, aluminum and PVC materials, we offer a complete range of full-bore valves suitable for a range of applications:Acids: hydrochloric, nitric, sulfuric, hydrofluoric, etc.

To ensure safety, the drilling pump is equipped with a safety valve in the outlet, which is able to control the ultimate pressure of the pump within the admitted scope.

The high-pressure safety valve is forged by high-quality structural alloy steel. As a kind of protection device and human safety device, it is generally installed on cementing devices, fracturing pumps, high-pressure operation piping, pressure vessel and devices under high pressure and high flow capacity. It controls the elastic force of the valve seat by adjusting the nut on the top. Once the pumping pressure or piping pressure exceeds the pre-established pressure value, the safety valve opens automatically to release the pressure. When the pressure value reaches the normal value, the valve rod will recover the position by spring and close the valve.

This product is used to reduce the high pressure inside the gas cylinder to make the gas usable. Widely applied in those industries such as welding, cutting and so on, the product can keep stable output pressure when input pressure and outlet flow change.
