2LA Series Fluid Control Valve (2/2 Way Stainless Steel)
Product Features
- 2/2 Way Normally Closed: Available in both Direct Acting (fast response) and Pilot Operated (large flow) types.
- Material: Body made of SUS304 Stainless Steel with H-grade heat-resistant coil.
- Sealing: Uses PTFE (Teflon) sealing material, suitable for various working media.
- Applications: Especially suitable for high temperature, hot water, and steam environments.
- Protection: Coil protection class IP65. Wiring options include Grommet (Lead wire) and DIN terminal.
Type Specific Features
- Direct Acting (2LA030/050): Compact size, light weight, fast response. High Pressure (H) type available (up to 2.0 MPa).
- Pilot Operated (2LA150~500): Piston pilot structure, low starting pressure, large flow rate.
