The water pressure regulator works on the principle of pressure reduction. It
is preferably for use in the provided water systems. The pressure regulator
consists of a housing, a piston or diaphragm valve with an adjustable spring
and a spring cap. The inlet pressure reaches the target value, opens the
piston or diaphragm against the spring force of the control valve and builds
up the output pressure. The output pressure is the controlled variable. When
exceeding the nominal value the valve closes, when there is a shortfall the
valve opens and thus the output pressure is kept almost constant. By changing
the spring tension, the spring setpoint can be continuously adjusted. The
pressure regulator is available in four versions:
• Version I brass housing with DIN DVGW and international drinking water
approvals
• Version II brass housing with inspectable strainer, DIN DVGW and international
drinking water approvals
• Version III stainless steel housing with DIN DVGW approval
• Version IV plastic housing with union connection G1/8" and G1/4" Type
TFU006 with plastic body and ported connection G 1/8 and G 1/4
