Design, function and technical data
To ensure the maximum life of the valve, the actuating mechanism must contact the stem at an angle P 30h. If this is not possible, a roller
lever valve is recommended.
Types E-25-310 and E-28-310: Port 1 must be used as the pressure inlet.
Types E-18-310 and E-18-510: All ports are interchangeable.
Valves E-18-310 and E-18-510 are available for use with vacuum (– 0.95 … 12 bar /–14 … 175 psi). Order number changes to E-18-310-Q
and E-18-510-Q.
