High Performance API609 Butterfly Valve MSS SP-67 Zero Leakage Electric Pneumatic Horizontal Pin
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.
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: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.
