High Performance Butterfly Valve
Design Feature
Horizontal pin: Reduce the exploding possibility of stem effectively under the internal unbearable pressure.
Disc: There is no stem through disc completely for less resistance and more flow capacity.
Stem: The design of two section of stem, can enhance the stability and resistance of disc effectively.
Guide bearing: It is made by nylon and can ensure that the shaft rotate in absolute center, to decrease friction and torque.
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
Standard
Valve body is designed to meet MSS SP-67 and API609.
Upper flange standards: Valve mounting flange and stem shall be per ISO 5211.
Flange Standard: GB 9113.1N ANSI 150 B16.5\JIS B2211.
Pressure Rating:
Bi-directional bubble-tight shut off to: 16 bar(230psi) DN40~DN600mm
And tested to 110% of full rating: 18 bar(260psi) DN40~DN600mm
Shell Testing:
The body strength can stand 150% of full rating: 24 bar(340psi) DN40~DN600mm
Main Features
Tight sealing and zero leakage under rated pressure(1.0Mpa~1.6Mpa).
Multi-sealing design separates valve body from working medium to ensure zero leakage.
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.
Scientific design for the sealing surface of valve seat makes a closed connection between the valve and the pipe flange without any additional ccessories.
Designed and produced based on multi-standard system, so the valve could be applied to various of flange and enjoy excellent interchangability.
All parts are embalmed, suitable for various complex work environment.
Others: According to customer requirements.
