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
