adjustable safety valve factory

HiP relief valves are now available with CE marking. These products will proudly be marked with the CE symbol, signifying they comply with the stringent requirements of the Pressure Equipment Directive (PED). To order, add -CE to your relief valve part number.

Standard W60 Adapter:The ‘standard’ adaptor is used on all models of short and long stroke W60 Series valves. Machined from SS 316L bar with a thick cross-section, the adaptor adds strength to the valve body and provides alignment for the stem. The outer perimeter seals to the valve body with an o-ring that is located forward to the product zone to minimize crevices. The product stem passes through the adaptor and is sealed to the adaptor with an o-ring. A Teflon® bearing guides the stem and takes up the mechanical loading imparted by hydraulic forces. This increases the service life of the stem seal. Adaptors are made in 1"-6" (25mm -152mm) sizes.

W80 Adapter: This adaptor is used to convert a ‘standard’ W60 series valve to a W80. The outer perimeter seals to the valve body with an o-ring that is located forward to the product zone to minimize crevices. The product stem passes through the adaptor and is sealed in the upper part and the lower part of the adaptor with o-rings. The space between the o-rings is flushed with a suitable liquid or steam. The Teflon® bearing is located in the flushed chamber. Adaptors are made in 1"-6" (25mm - 152mm) sizes. For vacuum-rated, extended shelf-life (ESL) applications, the W80A adaptor adds steam trace to the adapter-to-valve body connection.

Wiping Stem Seal Adapter: For high-risk and hard to clean product applications, the wiping stem seal fills the gap between the product zone and the traditional o-ring stem seal. The adaptor is a two-piece design to allow easy inspection or replacement of the wiping stem seal. The outer perimeter seals to the valve body with an o-ring that is located forward to the product zone to minimize crevices. A Teflon® bearing is used to guide and support the valve stem.

At iPolymer, we offer a wide-range of plastic valve products that also include pressure relief valve options to accommodate the requirements of industrial and commercial customers. The PTFE fully adjustable pressure relief valve we offer is one of our premier valve products.

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 (PRV). The single O-ring design enables the user to choose EP, Viton, or Kalrez (FFKM eq.) 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 (PVDF), Polypropylene (PP), and Anodized Aluminum (AA).

Although the ports are inline, this is not a "through flow" model where flow continuously passes through the valve. If this valve were to be installed in a flow line, it would shut off flow to the line completely and open only when the set pressure is exceeded. When the flow is in the opposite direction the valve becomes a check valve. When used as a relief valve it is typically mounted to a device to be protected such as a tank or other pressure containing device. If a flow stream needs to be protected from overpressure, then the valve is mounted on the side of a Tee, or at the end of a line branch where it will pass excess flow only when the valve opens. The outlet port of the valve is usually piped to a drain or discharged directly to atmosphere only if the liquid or gas is safe to be discharged without injuring personnel or damaging equipment nearby . For a true "through flow" model, see our model RVT05 which is a piston type that has three ports.

This valve is normally used for liquids, air, or gases which cannot be safely discharged to atmosphere. Where the discharge can be directed to the atmosphere, please refer to our
