Resilient Seated Gate Valve Large Size with Cap

Product Description

Product Description
valve for non-rising stem seal gate valves of the elastic base seat wedge type single ram, using direct channel structure. Dark stem design, the valve has the remarkable installation space small feature;
ram as ductile iron skeleton + high-performance rubber, EPDM, advanced plastic injection molding technology and mature vulcanization process. The adhesive strength, tensile strength and resilience of the rubber are guaranteed, and the rubber after vulcanization has no defects such as bubble, crack and dew iron. Its binding strength meets the requirements of DVGW, and it will never fall off even if subjected to frequent extrusion stress. The bonding strength shall not be lower than 1.725mpa when measured according to GB/T 11211 standard. Make sure that the gate plates are interchangeable and the valve can be operated with low torque for sealing effect.
gate on both sides of the guide rail with wear-resisting non-toxic engineering plastic (nylon), and gate valve is firm, good appearance, can accurate orientation, and greatly reduces the valve opening and closing torque;
high strength and high precision rolling stem, self-locking performance is good, and the stem nut and flexible shaft sleeve with precision, to ensure that the valve torque is extremely low, each parts material and the machining precision can ensure valve twice in the overload torque under the action of (according to EN1074.2) without any obvious damage, has the characteristics of high life;
gate seal USES three type O sealing ring seal, has the advantages of infinite (no pollution, small torque). The ultra-high surface finish of the stem ensures that the service life of the stem o-ring is five times longer than the normal process (stem machining).
stem nut cooperate closely with the ram, and to ensure that sufficient degrees of freedom, make instant valve open/close damper under the action of water pressure free adjustment, thoroughly overcome the bending stress due to the deflection deformation under the action, and can greatly reduce operating torque, increases the service life of the valve;
contact seal for spherical sealing face of the upper gate line, contact area is lesser, open/close the valve and out of the sealing surface of short time, reduce the valve operating torque, and achieve the best sealing effect. In the sealing test, there is no structural damage to the gate plate. The base of the gate plate is changed from the domestic single seal to the double bar line seal, which effectively prevents the gate plate's axial swing under the action of water pressure, enhances the sealing performance, and can achieve two-way "zero leakage".
jacket type rubber seal gate valves leading global modular design, can be realized with pressure change on sealing ring, without removing the valve from the piping is replaceable parts, do not remove the valve cover is easy to replace the valve stem, bring a lot of convenience to very case maintenance;https://membercenter.made-in-china.com/productmanage.do?xcase=view&prodId=dNjJVyuUlchL&queryGroupId=&queryCatCode=&pageSize=30&queryState=3&prodUpgradeActivity=
