RB 4000 Gas Pressure Regulator

SSV 8500 (FOR RB 4000 MODELS WITH INTEGRATED SSV 8500)

Maker: ITRON ( GERMANY)

CATALOG: RB 4000

Gas Pressure Regulator

The RB 4000 pressure regulator is designed for gas supply networks, district station regulation, industrial service regulation, and all applications where accurate pressure control, ease of adjustment, and fast response are required such as for burners, industrial ovens, boilers, etc.

It may be fitted with an integrated safety shut-off device type SSV 8500 or SSV 8600.

Operating principle of the shut-off valve

The safety shut off device have the task of automatically shutting off the gas flow in the downstream pipe system as soon as the pressure value increase or decrease beyond the preset values.

Shut-off valve with screw reset

The device consists of a valve body 10, a control head, a diaphragm assembly 4 – 15 and a stem-valve plug assembly 12- 18 which remain in a balanced position through a mechanical ball latching system.

The shut-off valve is triggered when the pressure value in the control chamber 5, that from the downstream pipe flow into this chamber through the sensing line 15 increase or decrease beyond the preset values, thus moving from its balancing position. In this action the SSV measurement diaphragm stem valve plug system switch. The stem 18 connected to the valve disc 12 triggers under the force of the closing spring 13 the valve disc to the orifice 8 by cutting automatically the flow of gas.

INSTALLATION WITH SAFETY SYSTEMS

The SSV must have a dedicated sensing line, whose point of sensing provides a representative pressure. An isolating valve on the sensing line is not permitted.
