Range of wall hung, gas-fired condensing combination boilers providing domestic hot water via a plate heat exchanger and pressure relief valve set at 3.0 bar. The supplies to both primary hot water and secondary are controlled via spherical valves. The boilers incorporate a filling loop assembly which incorporates a double check valve assembly (suitable for backflow protection against Fluid Category 3). Primary circuit: Maximum working pressure 2.5 bar. Maximum operating temperature 82°C. Secondary circuit: Maximum working pressure 10.0 bar. Maximum operating temperature 60°C
Range of gas fired condensing combination boilers providing domestic hot water via a plate heat exchanger. The cold inlet incorporates an angled spherical valve with a brass body, chromium plated brass ball and a lever operating member. The primary circuit incorporates an expansion vessel, isolation valves on flow and return, drain valve and a pressure relief valve set at 3.0 bar. Maximum working pressure of the primary circuit is 2.5 bar. Maximum working pressure of the secondary circuit is 10.0 bar. Maximum operating temperature for the secondary circuit is 55˚C. Cold supply only.
Hydraulic block assembly comprising a flow sensor, primary pump assembly, pressure relief valve preset at 3.0 bar and plate heat exchanger. Maximum working pressures: secondary = 10.0 bar and primary = 2.5 bar. Maximum operating temperature 80°C.
MJ (Multi jet) range of water meters with either ductile iron (MJF model) or brass (MJ models) blue epoxy coated bodies and EPDM rubber ‘O’-rings. Maximum working pressure16.0 bar. Maximum operating temperature 85°C.
Range of ‘Resident Valves’ with a DZR brass body consisting of water meter manifold, an isolation valve on the inlet, a pressure reducing valve (adjustable between 1.5 and 6.0 bar) and 2 non-return valves which are located on the outlet of the water meter manifold. The ‘Plus’ models are also supplied with an isolation valve on the outlet, which incorporates a drain tap. Maximum supply pressure 16.0 Bar. Cold water above ground use only.
Range of meter boxes incorporating a plastic manifold arrangement consisting of a stop valve with non-rising spindle , check valve (however the complete assembly has not been tested to demonstrate it provides adequate backflow) and concentric meter port. Some models incorporate a drain off or blacking plug. Connections can be compression or push fit (see model). For use with PE8-0 pipe to BS EN 12201 and copper to EN 1057. Maximum working pressure 16.0 bar. Cold water use only.
Range of hand wash and dryer units The flow is controlled by a solenoid valve activated via an infra-red sensor. The products are supplied with a non-verifiable double check valve assembly (suitable for backflow protection against Fluid category 3) for installation on the inlet. The double check valve assembly also incorporates a drain port, (located in between the cartridges), and an integral spherical valve. Maximum working pressure 10.0 bar. Maximum operating temperature 50ºC.
Range of flow and temperature sensors with stainless steel bodies. Maximum working pressure 10.0 bar. Maximum operating temperature 80°C.
Range of pushfit hose connectors with either plastic (white or black) or chrome plated brass bodies and EPDM ‘O’-rings. SHCV prefix models incorporate screwdriver operated servicing valves. All pushfit connections are for use with PEX pipe (manufactured to BS7291-3) and copper pipe (manufactured to EN1057). Barbed end connections are not approved for use with any hose. Chrome plated brass body models are also for use with PB pipe (manufactured to BS7291-2). Maximum working pressure 10.0 bar (servicing valve models only). Barbed end connections are open outlet use only. Cold water use only.
Range of pump inverters with plastic bodies, NBR rubber and EPDM rubber seals and ‘O’-rings. The products incorporate an inline resilient trim non-return valve. Maximum working pressure 13.0 bar. Cold water use only.
