Plunger-type valve

555 piston-type valve Name: piston-type valve AKA: plunger valve, soft seal plug valve, hard sealed off valve plunger type: UJ41SM soft seal, UJ41H / Y Hard sealing applications - UJ41H / SM plunger valve plunger closing valves open and close quickly combine the characteristics and advantages of no leakage shut-off valve, as a new structure, extensive use of new varieties. This product is widely used in the petroleum, power, chemical, fertilizer, metallurgy, machinery, pharmaceutical, printing and dyeing, paper and steam pipes, seals were used in metal and nonmetal, high temperature, wear, corrosion and other performance expanded its use range. Structural principle - piston type valve is a valve body, bonnet, stem, plunger seals, handwheel and other components; when the handwheel is driven through the stem of the plunger, the plunger top taper reciprocating cone clutch and seat surface finish of the valve opening and closing. In the valve between the plunger and seal with an interference fit, by adjusting the compression valve cover bolts, the seal ring is compressed, the inner ring tight against the piston valve chamber outer wall, so that the seals are radial component that generated the pressure of the fluid, thus ensuring the seal, to eliminate the external leakage. Since the seal with strong resilience, but highly toxic extravagant new sealing material, the sealing reliable and durable. Tapered seat and plunger sealing parts, using high quality materials resistant to extravagant, to ensure the life of the valve. Design Advantages - torque, and prompt action; high temperature, wear and corrosion resistance; cone to eliminate the internal leakage; easy maintenance; Parameters - Temperature: -20 ℃ ~ 250 ℃ ~ 425 ℃ Applicable Nominal: PN1 .6 ~ 4.0Mpa Diameter: DN15-DN200
