The GEMÜ 554 globe tap range is extended by a compact actuator with a piston diameter of 30 mm. This version is particularly suitable for the control of gases and liquids used in industrial plant and machinery.

The proven GEMÜ 554 angle seat globe valve range will include another actuator size from spring 2008. Its piston diameter is 30 mm, the total valve height to the pipe centre is only 81 mm. The installation length is 100 - 108 mm dependent on the connection.

The DN 6 to DN 15 valve bodies in 1.4408 and 1.4435 stainless steel are interchangeable with the GEMÜ 550 range. Other materials will follow in the course of the year. EPDM and NBR later also PTFE seat materials will be available.

The operating pressure is to max. 10 bar. The actuator is available in Normally Closed control function. The GEMÜ 554 30mm piston actuator compliments the existing small actuator of the GEMÜ 550 with its piston diameter of 28 mm. These small nominal sizes and outer dimensions make both valves particularly suitable for battery mounting in plant and machinery for the control of liquids and gases. Particularly in applications with higher operating pressures and slightly contaminated media they have an advantage over servo and indirectly controlled solenoid valves manufacturer whose small control holes can easily get clogged.

The GEMÜ 554 range with now four actuator sizes and piston diameters of 30, 50, 70 and 120 mm can be used for universal applications. All suppliers of actuators can be equipped with electrical position indicators, controllers and field bus systems to enable simple and quick integration in modern automation concepts.
