Berluto DRV725 Reducing Valve

The Valfonta Model 280 Steam Reheater is designed to elevate the temperature of liquids flowing through a central pipe. This innovative device injects steam through the upper flange, which circulates through strategically placed small holes in the nozzle. As a result, steam jets are generated, propelling the fluid into a low-pressure area and creating turbulence. This effective mixing of liquid and steam leads to a significant increase in temperature, accompanied by a rise in pressure. The Valfonta Model 280 is renowned for its exceptional reliability, as it operates without any moving parts.

The Medenus RSP254 Pilot Operated Gas Pressure Regulator and Shut Off Valve is designed for applications requiring outlet pressures from 10 mbar to 12 bar with an accuracy class of up to 1%. With three distinct pilot versions available, we ensure the ideal solution to meet your project specifications for inlet pressures up to 16 bar. The Pilot R70-10 is suitable for high-pressure applications, delivering outlet pressures from 500 mbar to 12 bar. This makes it particularly effective in industrial settings, gas furnaces, gas distribution, and for manufacturers of gas engines. The R70-20 has been specifically developed with an integrated 1:2 booster and an optional external I/P converter, enabling us to achieve various set point systems for gas engines. For low pressure applications, the Pilot R70-100 is an exemplary choice, functioning optimally between 10 mbar and 500 mbar outlet pressure with exceptional accuracy. It is predominantly used in city gas distribution systems but also finds its place in industrial applications.

The PREL100023 High Capacity Sealed Heating System Pressure Relief Valve discharges water off the system at a set pressure in the event of system over pressurisation (high for larger capacity systems) Reliance Valves 100 Series Pressure Relief Valves are made from hot pressed brass and are predominantly used to protect closed-circuit wet heating systems from overpressure. The outlet is one size larger than the inlet to ensure high discharge flow rates. It has a separate seal seating from the diaphragm to give improved scaling resistance and a cover which is made from OT58 brass. Available in a variety of sizes to suit most installations, it also has a pressure range from 2.5 - 5.0 bar, with the response pressure indicated on the twist cap. The valve size is determined by the heat output of the boiler as shown in the maximum heating capacity table. 

Features and benefits: 

- High flow design for larger capacity systems 

- Outlet is one size larger than the inlet for high capacity discharge 

- Provides protection against over pressurisation in wet heating systems 

- Diaphragm design gives improved resistance against scale 

- Cartridge design gives ease of service and replacement without the need to reset the response pressure 

- Set pressure range from 2.5 - 5.0 bar to suit any system requirement 

- High lift design for increased discharge capacity 

- Suitable for heating applications only
