Process Tank Pressure Regulating and Back-Pressure Reducing Regulators

Staitech are the exclusive Supply Partners in Ireland for the Zurcher range of Process Tank Blanketing Regulators.

Zuercher BR/BS Series Inline and angle pattern low-pressure regulating and relief valves are designed to control the inlet or outlet pressures in storage tanks, agitator tanks, centrifuges or vessels during inerting at start-up, blanketing during process or transfer of tank media.

Low-pressure, reducing and relief valves DN15 – DN100

mBar range between -200 to 1000 mbar
Nitrogen air blanketing and process regulation
Precise control and setting through large diaphragm area
Horizontal and Vertical installation requires no extra drain ports
DIN and ASME Flange options
TA LUFT VDI 2440
