Basic Information:
  • Can be used to quickly filling including pneumatic actuators and pneumatic ball valve body, the product of pneumatic actuators and body after shaft cohesion among them, the product of pneumatic actuator is equipped with imported pneumatic valve, pneumatic valve on inward and outward and circuit breaker, the product of the body after nut and warp of corresponding pipeline, valve body with internal sphere and the "O" ring, the product has two "O" rings and single in ball up and down on both sides, "O" ring and ball in pipe fittings manufacturer the middle of products has four chlorine packing, raw materials for plastic products of the body. The packing place of pneumatic three-way ball valve leakage prevention and elimination method
    1, should according to the working condition choose packing materials and type;
    2, according to the relevant provisions of the correct installation, packing should be by circle put pressure, joint should be into 30 ° and 45 °;
    3, life is too long, aging, damage of packing should be replaced in a timely manner;
    4, the stem should be straightened after bending, wear, repair, must be changed to the badly damaged;
    5, packing shall be installed in a specified number of turns and gland should be symmetrical uniform pressure, pressing sleeve should be preloaded gap more than 5 mm.
    6, the gland damage, bolt, articulated part should be timely repair or replacement;
    7, shall comply with the operational procedures, in addition to the percussive handwheel, normal force at a constant speed operation;
    8, should be symmetrical tighten gland bolts evenly, gland and stem too small clearance should be appropriate increase its clearance, gland and stem clearance is too large, gland should be replaced.
    / quickly close pneumatic ball valves, pneumatic ball valve pneumatic stainless steel plate/closed ball valve pneumatic ball valve stainless steel head/pneumatic ball valves, pneumatic ball valve flange plate pneumatic ball valve with stainless steel shaft/pneumatic power switch type stainless steel ball valves, pneumatic adjustment type stainless steel ball valve tube fitting manufacturer consists of ball valves, pneumatic actuators and other related accessories, selection of pneumatic valve drive control gate valves open and close, belonging to pneumatic type O as of ball valve, sealed performance is good. Total flow, simple structure, long service life, convenient maintenance. Pneumatic type O the ball valves perform appliance for structure concise and compact, good performance, large output torque characteristics. Also is equipped with pneumatic ball valve schedule trip switch, relay to transform the actual operation, and touch the data signals from both the passive, open and turn off of gate valves. Electric actuators are divided into single function and dual efficacy of two kind of way. Once the single function type depends on the advantage, switching power supply common failures occurred. It is on the basis of the needs of the automatic control system for automatic is on or off site. Widely used in chemical plant, refrigeration, papermaking industry and other manufacturing industries. It can not only control gas, liquid and steam material, also can control the characteristics of sewage and chemical fiber Product features:
    (1) small liquid blocking, pneumatic ball valve is one of all liquid blocking the small gate valves. Even reduce the pneumatic ball valve diameter, liquid friction resistance is very small.
    (2) thrust ball bearing can reduce the seat of the friction torque. Make the seat long-term operation stability spirit.
    (3) the high pressure gate valve sealing performance is good. Ptfe made of ductile materials such as sealing ring is easy to seal. Ball valve sealing ability to work with medium pressure increase with the increase of.
    (4) seat tightness. Because the pneumatic ball valve 14 tube fitting seat around, do not do exercise. Pneumatic ball valve seat filler sealing is not easy to destroy. Seal the ability to work with physical work increase with the increase of pressure.
    (5) for PTFE material has excellent self-lubricating bearing performance, the friction loss of the ball. Ball valves service life is long.
