Features of a Parker HPRV

Fluid Controls are leading suppliers of Parker products, including the Parker High-Pressure Relief Valve. Here, we explain the features of the HPRV and what makes Parker High-Pressure Relief Valves superior to other brands.

What is a High-Pressure Relief Valve (HPRV)

A High-Pressure Relief Valve (HPRV) is a safety valve used to limit the pressure in a system. The valve prevents pressure build up which can create a problem in the process leading to equipment failure or, in some cases, fire.

The High-Pressure Relief Valve from Parker provides an automatic protection mechanism for process instrumentation systems. Ideally suited for liquid or gas applications, it has multiple end connections available. Features of the HPRV include:

• Blow-out and chip resistant captured moulded seat design.
• Colour coded springs and labels which indicate spring cracking range.
• Lock wire feature which secures a given pressure.

Why choose Parkers HPRV?

The Parker proportional relief valve features eliminate the need for threaded connections as well as potential problems that may be associated them, such as PTFE tape. This is due to it having a 5.2mm (0.203inch) opening. It comes with either twin-ferrule A-LOK or single-ferrule CPI solidity tube fitting ends. Other types of end connection may be itemised by Parker HPRV features to suit the mechanism. Certified to the highest category IV level of the Pressure Equipment Directive (PED) the pressure valve requires no additional paperwork to save you time and money. The low friction stem seal design prevents friction which increases accuracy of cracking pressure and reseat pressure, making it the safest pressure valve on the market.

The business development manager for Parker Hannifin says that the introduction of the HPRV provides users with the means to select enhanced and accurate protection for pressure-containing systems operating from 10-6000psi. Approval from the European Directive gives this product an individual advantage over other competitors.
