| SMP-BCA Aseptic Mixproof Valve with
PTFE Diaphragm |
 |
|
SMP-BCA Body Combination 30. |
Application
SMP-BCA is an aseptic double seat valve with PTFE
diaphragm. It is available as a stop- or divert valve.
The valve is suited for aseptic operating conditions such as high
sterilisation temperatures.
SMP-BCA is special designed for aseptic applications with the highest
hygienic demands.
Working principle
SMP-BCA is operated by means of compressed air. The valve
is a normally closed (NC) valve.
Sterile stem sealing towards the atmosphere is ensured by a special
designed PTFE/rubber diaphragm unit. The PTFE diaphragm does not allow
product residues to build up on the product contact surface.
The product lines are separated by two sealings and a
sterile barrier chamber to avoid mixing of product and to ensure immediate
indication in case of a leak from one of the plug seals. Two small
pneumatic normally open (NO) valves control flow to and from the sterile
barrier chamber. The barrier chamber must be clean and sterile when the
main valve is closed.
The lower product lines on change over valves are
separated by a single seal plug, without sterile barrier chamber.
Standard design
SMP-BCA is based on the SMP-BC valve design. It consists
of actuator, bonnet, stem with diaphragm unit and valve bodies. The divert
version is a three body design.
The valve is assembled by means of clamp rings and a stem
clip system for easy maintenance.

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.
