The low pressure reducing valve ZM-R is a direct single-level pressure regulator. Pressure regulators for

tank gas supply react already in case of very small pressure reductions within a tank by increasing the gas

supply to the tank. If the pressure within the gas cushion is re-established, the pressure regulator closes.

All parts in touch with the product are

made of stainless steel 1.4571 / 1.4404 or

Hastelloy C. The valve pallet is equipped with a soft sealing made of perfl uoro elastomer (FFKM) or fl uoro

elastomer (FKM). The tightness of valve sealing fully complies with DIN 3230. Valve ZM-R is manufactured

without oil or grease. The valve works automatically and is vacuum tight. Valve sizes DN 15, DN 25, DN

50 and DN 100 / ANSI 1/2", 1", 2", 4" are available with fl ange connection as per DIN or ANSI. A threaded

connection (thread measured in inches) is possible for sizes DN 15 / ANSI 1/2" and DN 25 / ANSI 1". Please

ask for different types of connection.
