Valves provide complete engineering solutions, the trench gate sale, sale, sale of professional services. Product Name: trench gate Model: Z85X, Z81X drive: handwheel Connection: clamp structure form: groove seal structure: soft sealing pressure range: 1.0-1.6MPa Nominal Diameter: DN50-DN600 Material used: cast iron, ductile iron nameplate: male workers brand products described ordering process gate trench, trench fire signal valve closure is the fire service and achieve closure state electrical monitoring of special valves. Mainly used in sprinkler systems were the main pipe closure and closure state control. It also can be used for fixed fire extinguishing systems. Fire trench gate having a switching signal lightweight, reliable sealing, excellent elastic memory significant advantages and a long service life, the fire signal valve flange is widely used in construction, fire fighting, petroleum, chemical, power, food, medicine, textile , shipbuilding, energy and other industries pipe line as a regulator and shut-off devices. Groove signal in addition to a resilient seated gate valve closure beyond the advantages, and can be more intuitive display the valve opening degree in order to determine in more distant valve opening time to take corresponding measures. Open and close quickly and reliably, so often used in fire protection systems. Our introduction of the European high-tech valve manufacturing technology produced resilient seated gate valve using the valve overall compensation package of plastic deformation to achieve a good seal, valve seal bad customer service in general, leaking and rusting phenomenon. Fire trench gate signal characteristics: 1, the overall package of plastic: plastic gate with the overall package, its good performance and accurate coverage of geometry, to ensure reliable sealing and long life; 2, flat seat: the bottom of the pipe using the same flat-style seat design, does not produce debris siltation, more reliable seal; 3, corrosion resistance: cavity made of non-toxic epoxy resin coating to prevent rust and corrosion, not only for drink, and sewage systems are available; 4 , three "0" seal, valve stem three 0-ring seal, friction is small, lightweight switch, watertight trench gate signal fire main parameters: The main parts and materials No. Name Material 1 Body Ductile iron 2 valve balls iron, covered with NBR 3 4 bolts galvanized ductile iron valve cover gasket NBR 5 6 Stem Stainless steel 70-ring NBR 8 shaft cover 9 Dust NBR 10 Ductile cast iron hand wheel fastening nut 11 Galvanized technical parameters Sealing test pressure rating 1.0MPa 1.6MPa 1.5MPa 2.4MPa Operating temperature 0-80 ℃ For medium water, gas and other suitable medium temperature pressure seal test strength test water, oil, etc. <= 100 ℃ 1.0 / 1.6MPa 1.1 / 1.76 MPa 1.5 / 2.4MPa provided various types of fire equipment, according to "architectural design code for fire protection" GB 50016-2006, "Building Water and Heating Engineering Construction Quality Acceptance" GB50242-2002 and other relevant national standards and ANSI, JIS, BS, DIN and other foreign design and manufacturing standards and inspection and acceptance of related products: signal valve More Related Products: electric soft sealing valve
