The globe valve with independent isolation test joints in accordance with DIN 16272
Nominal pressure: up to 40 MPa

Description of the instrument valve
Type A instrumentation valves with LH/RH (left-handed/right-handed) unions, while Type B has shafts, threaded nipples and union nuts for mounting brackets. Instrumentation valves with test fittings are mainly used to connect working pressure measuring instruments and pressure gauges with test fittings to pressure pipes at the same time.
For DIN 16271-compliant instrumentation valves, the test shaft uses a lenticular seal and a top-end nut seal; for DIN 16272-compliant valves, the test shaft is passed an additional The stem is isolated separately. The instrument valve is silicone free.
