Pressure Regulator for Water, with Female Thread
Description
Regulator independent of inlet pressure, made of gunmetal, with strainer of stainless steel.
Regulators up to 10 bar outlet pressure equipped with diaphragm, all others are piston-operated.
particulary all regulators RWI-..C with outlet range 1.5 ...6 bar
preferably water or drinking water, but also compressed air, neutral liquids and non-corrosive gases.
Especially suitable for air are regulators RWI-..D. It has to be considered that these regulators are non-relieving.
1 bar, between inlet and outlet pressure
Mounting position any, preferably vertical
between supply and outlet pressure should not be greater than:
20:1 for RWI-..A, 10:1 for RWI-..D, 6:1 for RWI-..G/H, 3:1 for RWI-..I
G¼ on both sides of the body for outlet pressure, ports are closed with screw plugs.
according to ATEX94/9EG, EN1127, EN13463 for zone 1, 2, 21 and 22
according to EU directives DGRL/PED for liquids and gases of group 2
0 °C to 80 °C / 32 °F to 176 °F
Screw standard
according to DIN ISO 228
