Accessories and
optionals A fine mesh filter is provided, to prevent dirty contamination of the seal seat. However, an
external strainer must be installed upstream of the valve. Brass models are available without
internal filter only.
Inlet pressure chamber is provided with bilateral G1/4 gauges, to connect manometers,
pressure switches, leakage tester or other gas equipments. Flanged models are provided with
gauges in the outlet chamber too. Brass models are available without gauges only.
Models from DN65 to DN150 are provided with G1/8 connection on the bottom for closed
position indicator micro-switch (on request from 3/4" to 2"). To install the micro-switch the
installing kit must be required.
The threaded models Rp11/2 and Rp2 can be provided with flanged connections using an
optional kit.
