By the valve body, valve cover, stem, plunger, handwheel and other components.When the handwheel is rotated, the plunger is driven by the stem to reciprocate up and down between the two sealing rings to open and close the valve.Because the sealing ring is made of new very metal material (PTFE), it has the performance of withstanding long-term high temperature and high pressure without losing elasticity, and the contact area between the plunger and the sealing ring is large. Moreover, the sealing ring system has good performance of mixed materials, so the sealing is reliable and durable.The valve is suitable for pipelines of water, gas, oil and other media with pressure of 1.6-4.0Mpa and temperature below 250℃ in metallurgy, fire protection, chemical industry, construction, chemical fertilizer, light industry and other industries.
