Reliance RWC TPR15 Pressure & Temperature Relief Valve 1/2

Reliance RWC TPR15 Pressure & Temperature Relief Valve 1/2" x 15mm 6 Bar - PTEM550857

The Reliance Water Controls (RWC) TPR15 Pressure and Temperature Relief Valves are compact devices meticulously engineered to safeguard against overpressurisation within unvented hot water systems. This crucial protection comes into play if the temperature or pressure controls fail. These valves are designed to be installed at the upper section of a hot water cylinder, where the highest temperatures can typically be found. In the event that the system temperature exceeds 95°C, the wax mixture within the temperature probe's element expands, causing the valve to lift off its seat and release water to waste. This process effectively alleviates excess pressure within the cylinder. Additionally, if the water pressure increases without a corresponding rise in temperature, the valve remains closed until it reaches the set pressure of the relief mechanism, at which point it opens to relieve the excess pressure. Certain models feature a PTFE coating on the MBSP inlet thread, significantly enhancing installation efficiency. ### Features and Benefits: - Provides protection against temperatures exceeding 95°C - Prevents dangerous overpressurisation - Twist-top cartridge design facilitates easy servicing - Available in a variety of pressure settings and probe lengths - Some models include a PTFE coating for added convenience ### Specification: - **Size:** 1/2" x 15mm - **Connections:** BSP Male Inlet x Compression Outlet - **Materials:** Brass - **Medium:** Hot water only - **Set Pressure (Set & Locked):** 6 Barg - **Temperature Relief:** +90 to 95 °C - **Discharge Capacity:** 10 kW - **Probe Length:** 95 mm - **Product Code:** PTEM550857 - **Notes:** Includes PTFE, WRAS approved Ensure the safe operation of your unvented hot water system with the RWC TPR15 Pressure and Temperature Relief Valves, an essential investment for any modern heating system.

FSKRDS - Sanitary Rupture Discs

FSKRDS - Sanitary Rupture Discs

The FSKRDS Sanitary Rupture Discs are a compression-loaded disc or reverse-acting disc, scored around the circumference. This disc has been designed to meet the high quality standards required by 3-A SSI, whose aim is to ensure public health through hygiene equipment. The FSKRDS model is particularly suitable for the Pharmaceutical, Food, and Biotechnology industries and represents the state-of-the-art for these sectors. This disc is entirely made of AISI 316L stainless steel (or other alloys upon request of the client). It’s smooth surface makes it particularly suitable for C.I.P. and S.I.P. treatments to maintain aseptic conditions. PTFE gaskets, which are certified in compliance with FDA and USP class VI, 3-A, and Eu 10/2011 regulations, facilitate the installation in Clamp fittings (sanitary, Tri-Clamp, Tank Connection). The operating pressure modifies the camber of the convex disc only when reverse pressure is reached. Upon reversal, the disc opens completely in a few milliseconds along the score line, thus preventing fragmentation from forming. The FSKRDS disc, with its innovative design, can be used with liquids only and can resist both vacuum and high pressure.

CONCOA 493 Series Regulator

CONCOA 493 Series Regulator

Six-port, stainless steel, single-stage regulator for ultra-high pressure applications

The CONCOA 493 Series regulator provides primary pressure control for ultra-high-purity and corrosive gases in applications requiring extreme pressures. Using a robust piston assembly instead of a diaphragm, it safely handles high inlet pressures. Factory-installed options allow it to be configured as line regulation or a single-station manifold, with or without purge, low-pressure alarm, or multiple inlets.

Features:

  • Large piston sensor manages pressures up to 6000 PSIG (415 BAR)

  • CAPSULE® seat with integral 360° filtration

  • Front and rear panel mount for easy installation

  • Helium leak integrity verified via spectrometry
