CKD LAD Diaphragm Type Cylinder Valve (Rc3/8-Rc1)

CKD LAD Diaphragm Type Cylinder Valve (Rc3/8-Rc1)

CKD LAD diaphragm-type air-operated cylinder valves isolate the actuator from the flow path for grease-free control of pure water, water, air and N2.

Key features

  • NC, NO and double-acting types, Rc3/8 to Rc1
  • PPS resin or SCS13 stainless body; PTFE or EPDM diaphragm
  • Lightweight PPS actuator; diaphragm isolation keeps the wetted path grease-free
  • Options: 1 (flow adjustment), B (mounting plate), 1B (both), e.g. LAD1-15A-CB
  • PTFE type: 0-0.3 MPa, fluid 5-90 C (SCS13 body 5-100 C); EPDM type: up to 0.5 MPa
