[Valve features]
1, In the valve plunger and the seal by interference fit, by adjusting the flange bolt preload, the lateral force and the body sealing ring generated by the compression of the cylindrical hole surface and the plunger seal, thus ensuring the sealing performance of the valve, to prevent the external leakage
2, Because the seal ring uses the resilience strong, the abrasion resistance high non-toxic new seal material, therefore the seal is reliable, durable, thus enhances the valve service life
3, The valve combines the advantages of non leakage valve and closing valve opening and closing characteristics, become a new structure, wide range of new varieties
[Adaptive condition]
Plunger globe valve with sealing ring made of new non-metallic materials, has the properties of high temperature and high pressure as long without loss of elasticity, and the contact area between the plunger and the seal, and sealing performance of ring mixed material is good, therefore, the seal is reliable, durable. Mainly used in metallurgy, power industry, chemical industry, refining, chemical fertilizer, light industry, food and other industries.
