Product Description

 Diaphragm Pressure Reducing Valve with in-built Filter

The pressure reducing valve with diaphragm TWIST is an automatic valve that reduces and stabilizes the pressure of a uid in a water distribution conduit to a preset value. The use of this device is necessary if the maximum possible pressure at any point in the water distribution system can reach or exceed the relative maximum allowable working pressure, or if apparatus and equipment that function exclusively at lower levels of pressure are connectable. The square cell ltering cartridge inside the reducing valve is designed to separate foreign particles in suspension such as sand, rust akes, calcareous fragments, etc.; by means of a physical barrier. The dirt transported by water could cause corrosion in the water pipeline and wear down the pressure reducing valves or any other device installed downstream. The enhanced mechanical strength of the shell and its internal components renders this valve particularly suitable for the use in water supply systems outside buildings (EN 805) where the water pressure may reach values as high as 25 bar. Further, the compensated seat nulli es the in uence itdhaet vsatrilatibonosruinmu.pstream pressure may have on the downstream pressure. The diaphragm in pre-shaped and folded EPDM rubber (peroxide cured) reinforced with high mechanical strength textile in conjunction with the anti stick-slip Perox EPDM rubber dinamic o-ring, allows a precise and long-lasting pressure regulation. The broad internal cavities with smooth nishing surface have been designed to create a minimum ow resistance, limiting vibrations and load loss. The cavities pro le ensures a low noise level even in extreme terms of use. The innovative regulation knob with indicator allows to simply and quickly set the device, with no need of tools. The graduating scale, in bar or psi, repeated 3 times on the knob, allows to easily read the value in any installation condition. The pressure reducing valve TWIST is available with outlet pressure setting range 1·6 bar or 1·12 bar. The pressure reducing valve TWIST is easy to be disassembled and reassembled for the periodical maintenance, such as cleaning or substitution of the incorporated strainer.The TWIST pressure reducing valve with diaphragm is used in air conditioning systems, sanitary installations for water supply, irrigation systems, compressed air (not oil mist) supply systems, water supply for human consumption within buildings, according to EN 806-2, and for re extinguisher networks. (P.S. It should nevertheless be borne in mind that local government standards for re protection must always be observed.). This product adheres to the standards set forth by the European health authorities for the transport of alimentary uids and drinking water and it is approved WRAS (UK Water Regulations Advisory Scheme). ATTENTION: THE PRESSURE GAUGE INSTALLABLE ON THE PRESSURE REDUCING VALVE INDICATES THE ALREADY-REDUCED PRESSURE (Ps) OF THE OUTGOING LIQUID. The pressure reducing valve is available with or without gauge.
