Diaphragm valve with butt weld ends or clamps; in straight-way, Y or T pattern, or as a multi-port valve; shut-off and sealing to atmosphere by confined and supported diaphragm. No dead volumes, suitable for sterilisation, SIP/CIP-compliant design, position indicator. All moving parts are separated from the fluid by the diaphragm. Maintenance-free.

Benefits
Reliable sealing ensured by one single sealing element (the diaphragm) which provides hermetic sealing to atmosphere and absolutely tight shut-off. The specially enclosed diaphragm ensures long service life and high operating reliability.
Special design: All moving parts are separated from the fluid by the diaphragm.
Compact valve design with integrated actuator requires minimal space.
Actuator interface allows straightforward retrofitting of limit switches.
Higher sterile requirements can be met with standard design by controlled discharge of exhaust air
Pneumatic stainless steel actuators meet stringent requirements in sterile applications.
High operating comfort thanks to visual position indicator, also with the limit switch enclosure mounted
Low-friction piston seal minimises friction losses and ensures smooth movement of the pneumatic actuators.
The valve hydraulics without dead volume offers optimum conditions for high-purity fluids.
Optimised functional reliability of the diaphragm thanks to balanced diaphragm suspension
Reliable processes ensured by limit switches in IP64 stainless steel enclosure for actuators
Readily identifiable position: integral red position indicator on manually operated valves and pneumatic actuators
The valves are self-draining and CIP/SIP-compatible, making them ideally suited for pharmaceutical applications
Laser marking simplifies valve installation and identification of drain angle.
