Product Description
- Ideal for safe control when venting and de-venting compressed air systems – e.g. in process plants, machine controls, shut-off devices or for safety shutdowns in automation.
- The HEE‑D‑24 electric switch-on valve from Festo reliably controls the supply and exhaust air flow in pneumatic systems (3/2-way, monostable, pilot-controlled).
- The all-metal construction of the D series ensures high robustness, while NBR seals and LABS compliance enable use in sensitive industrial areas.
- Valve type – Electric on-off valve, 3/2-way, closed, monostable with spring return
- Design – piston slide valve with soft seal, pilot-operated, without throttleable exhaust air
- Actuation – electromagnet (24 V DC, 2.5 W) with detent manual override and mechanical spring for reset
- Operating pressure range – 2.5 to 16 bar (equivalent to 0.25 to 1.6 MPa)
- Flow capacity – C value 27.6 l/s·bar, normal flow approx. 6,500 l/min (according to DIN 1343)
- Media requirements – compressed air in accordance with ISO 8573‑1:2010 [7:4:4] or inert gases, oiled operation possible
- Material & environmental characteristics - Die-cast aluminium, NBR seals, RoHS compliant, LABS/PWIS-free (VDMA24364‑B1/B2‑L), corrosion protection class KBK 2
- Temperature range: –10 to +60 °C (medium & environment)
- Assembly & connection – pipe installation, connection ports: 1 = G1, 2 = G1, 3 = G3/8, plug form C according to DIN EN 175301-803
