Design Feature

  1. Horizontal pin: Reduce the exploding possibility of stem effectively under the internal unbearable pressure.
  2. Disc: There is no stem through disc completely for less resistance and more flow capacity.
  3. Stem: The design of two section of stem, can enhance the stability and resistance of disc effectively.
  4. Guide bearing: It is made by nylon and can ensure that the shaft rotate in absolute center,to decrease friction and torque.
  5. The seat with backrest: It is consisted of inner backrest and outer rubber.the backrest can withstand the deformation of seat when it is scoured and squeezed to extend service life.

LPB14 High-Performance Butterfly Valve Design Feature


  1. Valve body is designed to meet MSS SP-67 and API609.
  2. Upper flange standards: Valve mounting flange and stem shall be per ISO 5211.
  3. Flange Standard: GB 9113.1N ANSI 150 B16.5、JIS B2211.
  4. Pressure Rating:
  5. Bi-directional bubble-tight shut off to: 16 bar(230psi) DN40~DN600mm
  6. And tested to 110% of full rating: 18 bar(260psi) DN40~DN600mm
  7. Shell Testing:
  8. The body strength can stand 150% of full rating: 24 bar(340psi) DN40~DN600mm

Main Features

  1. Tight sealing and zero leakage under rated pressure(1.0Mpa~1.6Mpa).
  2. Multi-sealing design separates valve body from working medium to ensure zero leakage.
  3. Main parts are designed to fit exactly into each other to ensure a better sealing, smaller torque, bigger flow, lower fluid resistance as well as flexible two-side flow.
  4. Scientific design for the sealing surface of valve seat makes a closed connection between the valve and the pipe flange without any additional ccessories.
  5. Designed and produced based on multi-standard system, so the valve could be applied to various of flange and enjoy excellent interchangability.
  6. All parts are embalmed, suitable for various complex work environment.
  7. Others: According to customer requirements.
