DIN3352-F4 NRS Brass Gland Resilient Seated Gate Valve, DN50-DN1200

Gate valve (gate valve) is a opening and closing parts of the gate plate, the direction of movement of the gate plate and the direction of the fluid is vertical, the gate valve can only be fully open and fully closed, the discomfort of the door parameters vary, usually 5°, medium temperature is not high, 2°52'. Improve its technology, make up for the sealing surface Angle in the process of the deviation, this kind of gate is called elastic gate.

Products Details

  DIN3352-F4 NRS Brass Gland Resilient Seated Gate Valve, DN50-DN600 Features ² The ductile iron core is fully vulcanized with EPDM rubber, no iron parts are exposed to the medium and the excellent rubber vulcanization prevents creeping corrosion underneath the rubber. ² Guides in the wedge and on the valve body ensure a uniform closure, safe operation ensured as the guides prevent overloading of the stem. ² Stainless steel stem with rolled threads for high strength. ² The valve can replace stem seals under pressure. ² Full bore. ² Body inside and outside fusion bonded epoxy coating with excellent corrosion resistant performance.   Standard
