Design features:Product range
  1, normally closed state: disc hard seal pay on seat convex platform, forming a hard seal, and embedded in the disc with soft seal seat face tight pressure, formation of the second seal, double quality sealing structure ensures zero leakage of the valve, because the disc opened balance hole again, make the valve in the closed and open, the disc by smaller force, also make the valve opened and closed with a smaller torque.
2, throttle discharge state: disc sealing pay leave the seat, because in the disc has a balance hole, make very light valve opens. After the valve opens, medium, the impurity in the pipeline flow through the valve cover, valve seat, at the same time realize the throttling and sewage. Disc and seat sealing surface using the set of mat to the flow direction of medium Angle change, have self cleaning function, make the seal can't pay with impurities.
3, closed: discharge after close the valve by the media in pipeline medium from the set of access to the seat cushion Angle, flow resistance coefficient increases, the flow speed, flow direction of medium Angle change direction, produce eddy current, the seat face medium radial force increase, realize the hermetical seat purging. Disc sealing pay close to the seat, the set of cushion and seat channel fit clearance flow direction of medium to prevent larger particles seal pay, combined with the further increase of flow velocity and transverse force of purging medium, the valve closing seal pay has completely clean of impurities, ensure the sealing performance of valve after discharge, thus further ensure drainage after sealing can achieve without leakage. Thus greatly improving the ability and prolong the service life.
1,Nominal pressure:1.6MPa
2,Working medium: water, gas and oil
3,Working temperature:-20℃≤T≤150℃
4,Pipe thread: ISO228 standard
Product overview:
  1, this valve is a new type of throttling, globe, emptying the throttle valve adopts the cage fan legion, a multistage throttle effect, throttling effect, reliable sealing, convenient operation and maintenance, etc.
2, valve adopts double seal (hard and soft seal) can make the sealing is reliable, hard alloy cover more air flow scouring resistance, wear resistance, double seal can achieve zero leakage in high pressure gas medium conditions. The valve long service life.
The 3, valve seat sealing surface taper sealing and dirt on the surface of the valve itself clean attached to the seal.
4, the balance was installed on the disc of the valve hole, piston seal, to ensure the full differential pressure stability under the condition of opening/closing operation, flexible and convenient open open-close torque is small.
5, filler used with the sealing ability of v-shaped packing structure, without adjustment, features very light open and close. An auxiliary sealing grease injection structure is set in the packing, the packing seal valve performance is reliable.
6, this valve can be on-line maintenance, replacement of packing line can take pressure condition and a series of wearing parts.
7, this valve at the bottom of the valve set up large drainage hole, when it is necessary to open, clean up dirt in the valve.
8, drain valve disc of cylindrical high place with o ring, when opening/closing, since the cleaning function and sealing drainage when have the function of throttling depressurization.
