Basic function of pressure relief valve

Pressure relief valves, also referred to as safety relief valves, are triggered to open at a designated pressure and expel fluid until the pressure reduces to an acceptable level. In its operating condition, this pressure relief valve is typically closed until upstream pressures increase to a predetermined set pressure. When that set pressure is reached, the valve opens, and continues to open wider, enabling additional flow as the pressure increases. The valve starts to close again when the upstream pressure drops to a few PSI below the set pressure.A 100-percent pure PTFE Valve Body and Valve Plug are used in the manufacture of the iPolymer Pressure Relief Valve. The single O-ring design enables the user to choose EP, Viton, or Kalrez  according to the flowing media. 

The PRV we offer is factory configured for a pressure between 10 psi and 90 psi.Within the above-mentioned pressure range, this PTFE pressure relief valve is fully adjustable by the means of a simple adjustment to the upper Socket Hex Adjustment Screw and then a simple lock-in-place with the associated locking nut. The three upper housing and lower base configuration options available with our PRV are.Polyvinylidene Fluoride, Polypropylene, and Anodized Aluminum.Diaphragm valves are also called membrane valves and consist of a valve body, diaphragm, a minimum of two ports, and a seat which is closed by the diaphragm. Diaphragm valves are manufactured as pneumatic or automated devices. They are often used as shutoff valves within process systems for the biotech, food and beverage, and pharmaceutical industry sectors.

Our PTFE diaphragm valves offer the significant benefit of having a high cycle life, which enables them to stay operational at an optimum level longer than other types of valves manufactured from other materials. When it comes to diaphragm valves used in the pharmaceutical industry, PTFE offers several distinct advantages.This benefit enables PTFE diaphragm and membrane valves to operate safely with a range of chemical compounds. This makes these valves highly versatile and useful for a variety of experiments, tests, and manufacturing procedures.

These properties are ideal and crucial for preventing wear and tear in pharmaceutical manufacturing conditions. The benefits include reduced downtime from maintenance operations and lower part replacement costs.PTFE possesses low surface adhesion as opposed to other materials that may develop issues related to surface adhesion. As a result, PTFE diaphragm and membrane valves do not stick to powders or pills in pharmaceutical applications. In addition, coagulation is minimized when working with liquids.
