DIASTAR Six, Ten and Ten Plus valves are diaphragm valves with a two-way pneumatic actuator. They are used to regulate, shut off, control and monitor flow rates. Thanks to their simple operation and optimised construction, they are ideal when conveying contaminated, aggressive or abrasive media,
DIASTAR Six
An affordable and long-life solution for elastomer diaphragms with a medium pressure of up to 6 bar. The actuator is compact and combines high quality with the basic functions of a pneumatic actuator. It is available with fail-safe shut-off control function (FC), but does not include any additional accessories.
DIASTAR Ten
Ideal for standard applications with a media pressure of up to 10 bar. Simple integration into the plant automation is possible via the appropriate interface. Available with Fail Safe to Close (FC), Fail Safe to Open (FO) and Double-Action (DA) control functions. PTFE diaphragms can be used for aggressive chemicals.
DIASTAR TenPlus
This actuator is intended for high-performance applications requiring high closing forces. With this actuator it is possible to regulate up to 10 bar media pressure on both sides, such as in ring pipe systems. Available with Fail Safe to Close (FC) control function as well as in all diaphragm and pipe materials. An accessory interface is integrated for easy system integration.
DIASTAR Sixteen
This is the most powerful actuator in the GF Piping Systems range. The high shut-off power in combination with the special housing nut ensures safe regulation of media pressures up to 16 bar in water applications. The actuator is equipped with an integrated accessory interface for system integration and is also available with fail-safe closing (FC), fail-safe opening (FO) and double acting (DA) control functions.
