Product features

  • 1. Safer use

      Unique C-type valve core and three eccentric structure, no middle chamber design, avoiding valve chamber Accidents due to pressure rise caused by medium accumulation; Single valve seat structure is adopted, The sealing failure caused by the blockage of the spring valve seat structure by impurities is avoided.

  • 2. Long product operation cycle

      The sealing surface of the valve is free of friction, eliminating wear, increasing the maintenance interval of the valve, and the valve operation cycle is long.

  • 3. Lower media loss

      Fixed valve seat and torque seal are adopted, and the product seal is superior to the requirements of the industry standard (bs6364).

  • 4. Reduce maintenance costs

      Top mounted structure can be maintained online, saving maintenance time and cost;

      All parts of the valve have universal interchangeability and replaceability; Field replaceable seals.

  • 5. Low dissipation

      The valve adopts low escape sealing material and dynamic packing sealing structure. The valve meets the requirements of iso15848-1, Ta Luft and EPA method 21.
