Crane Fluid Systems has launched a new portfolio of Public Health Valves, comprising five products that are uniquely designed for hot and cold water systems. The range is WRAS approved and includes Thermal Circulation Valves (TCVs), Pressure Reducing Valves (PRVs), Check Valves, Non-Return Valves and Lever Operated Double Regulating Valves. Most are available in multiple sizes with pressure ratings from PN16 up to PN25.

The new Crane Fluid Systems Public Health range consists of the following valves:

Thermal Circulation Valves (TCV)

The Crane Fluid Systems TCVs (D2890 & D2880) provide self-balancing, thermostatically controlled regulation of flow and thermal disinfection, assisting with protection against Legionella. They operate by keeping the temperature of domestic water systems periodically above 70oC to ensure the bacteria cannot develop and reproduce into the “Legionella Pneumophila.”

Pressure Reducing Valves (PRV)

The new Crane Fluid Systems range of PRVs ensure that the appropriate and comfortable water usage pressure is available at all times. They enable the control of pressure from boosted cold water supplies to match site requirements. The new PRV range is available as follows:
D1716 (1/2" to 2", PN16) and D1725 (1/2" to 2", PN25)
DM1716 (DN65 – DN150, PN16) and DM1725 (DN65 – DN150, PN25)
This wide range of valves means that the Crane Fluid Systems can now offer PRVs that will regulate water pressure across a variety of different applications.

Single & Double Check Valves

The Crane Fluid Systems Single & Double Check Valves permit flow in only one direction and close automatically if flow reverses. They are suitable for domestic and commercial water systems such as taps, mixers and showers. Spring assistance enables the valve to be installed in horizontal or vertical pipework, while simultaneously preventing backflow.
The Single Check Valves are available as follows:
D120W D120CW (PN16) and D125W (PN25)
The Double Check Valves are available as follows:
D220W & D220CW (PN16) and D225W (PN25)

Swing Check Valve

The new Swing Check Valve (D140W) can operate in horizontal or vertical pipelines provided the flow is in an upward direction. A disc inside the valve allows the liquid to flow through comfortably, but shuts when the liquid attempts to change direction, thus preventing back flow.

Non-Return Valve

The Crane Fluid Systems Single and Double Non-Return Valves (D130W & D230W) are specifically designed to allow flow of fluid in one direction only and to prevent reverse flow of fluid and contamination in domestic cold water supplies. They are now available in large sizes from DN50 to DN250.

Butterfly Balancing Valve

The Crane Fluid Systems Butterfly Balancing Valve (DM925LW) contains a double regulating feature than enables the valve to be used for isolation and to be reopened to its pre-set position to maintain required flow rate. It is an ideal choice because of its lightweight but robust structure.
