Type 186 - DN 12-15
The 186 is a pneumatically operated diaphragm valve of reduced dimensions and particularly compact structure, ideal for use in confined spaces.
COMPACT DIAPHRAGM VALVE
• Connection system for solvent weld and threaded joints
• Extremely compact construction
• Internal operating components in metal totally isolated from the
conveyed fluid
• Valve stem in STAINLESS steel
• Easy to replace diaphragm seal
• Corrosion-proof internal components
• CDSA (Circular Diaphragm Sealing Angle) system offering the following
advantages:
- uniform distribution of shutter pressure on the diaphragm seal
- reduction in the tightening torque of the screws fixing the actuator to
the valve body
- reduced mechanical stress on all valve components (actuator, body and
diaphragm)
- easy to clean valve interior
- low risk of the accumulation of deposits, contamination or damage to the
diaphragm due to crystallisation
- operating torque reduction
