阿尔法拉瓦尔SMP-BCA双栓混合阀门PTFE膜式说明书

The Alfa Laval SMP-BCA Mixproof Valve is operated by means of
compressed air from a remote location.This aseptic valve is a normally closed(NC)valve.A specially designed diaphragm unit with a PTFE face and reinforced EPDM rubber backing ensures sterile steam sealing prevents intrusion from the atmosphere and does not allow product residues to build up on the product contact surface.The product lines are separated by two seals and a sterile barrier chamber to prevent mixing the products and to ensure immediate indication
in the event of leakage from one of the seals.Two small pneumatic normally open(NO)valves controlflow to and from the sterile barrier chamber.The barrier chamber must be clean and sterile when the main valve is closed.Standard design
The Alfa Laval SMP-BCA Mixproof Valve consists of valve bodies, bonnet,stem with diaphragm unit,PTFE EPDM or FPM plug seals and an actuator.The valve is assembled by means of clamp rings and a stem clip system for easy maintenance.It is also available as a shut-off valve.The valve can also befitted with the Alfa Laval ThinkTop V50 and V70for sensing and control of the valve.

Leakage connection:
R3/8"(BSP),external thread.
Caution,opening/closing time:
Opening/closing time will be affected by the following:
-The air supply(air pressure).
-The length and dimensions of the air hoses.
-Number of valves connected to the same air hose.
-Use of single solenoid valve for serial connected air actuator functions.
-Product pressure.
