SMP-BCA

Aseptic mixproof valves featuring a double seal design

 
Ideal for handling sanitary process flows through matrix piping systems, SMP mixproof valves are standardized, cost-effective alternatives to Unique mixproof valves.
 

Concept

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 specially 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.
