Pinch valves from Schubert & Salzer Control Systems provide superior results when working with difficult media or under sterile conditions. The valves range from DN 15 to DN 50 sizes, and provide reliable shut off and control of fluids with granular and abrasive particles as well as viscous, pasty and aggressive media.
Schubert & Salzer Control Systems have fundamentally re-engineered this series to introduce the new 7078 pinch valves and 7079 pinch control valves. The key improvements includes a very compact construction with rotating piston actuator. All wetted metal parts made from 1.4435 1.4408 stainless steel body, use FDA-compliant seals and can withstand working pressures up to 6 bar. The FDA-compliant sleeves are reinforced woven fabric to increase service life, and are made up of materials made from NBR or EPDM.
The installation length of these pinch valves is the same as that of the preceding range. Furthermore, the valve actuation of the previous series, including piston rod and head section, can still be used. The plunger simply needs to be exchanged when making the modification.
Hand wheels and piston actuators (optional with pilot valve) powered by air, water, mineral oil and other media for operating the pinch valves are still available. In the
The pinch control valve version 7079 is combined with a top-mounted, integrated pneumatic, electro-pneumatic or digital positioner for very precise control tasks.
By using the 7078 stainless steel pinch valve and the 7079 stainless pinch control valve with an integrated positioner (shown in this image), even difficult media, such as fluids with granular and abrasive particles or highly viscous fluids can be shut off and controlled under sterile conditions.
