The valve consists of a pneumatically pistonactuator with return spring, a stainless steel body and PTFE bellows. The PTFE bellows areused for the separation of the medium. Withthe appropriate installation (body to bottom)the valve is self-draining. The materials usedand the internal contours are simple to clean(CIP and SIP). The valve is suitable for foodtechnology. The modular structure permits configuration with different armatures and customizedport connectors. The pneumatic actuatoris servo assisted by a pilot valve, a valve block or similar.
