Gauge valves
Developed for high pressures and sudden temperature changes, Boscarol gauge valves are ideal for regulating or interrupting the flow of supply or exhaust fluids, thus supporting pressure gauges. They are manufactured with high quality materials which are selected, treated and processed according to each specific condition of use.
Technical features
Available in three tuned up solutions: OT/58, AISI/316, ASTM A 105
Operating parts in zinc-coated ASTM A 105 steel can be provided for the AISI/316 series
Double version with 2 or 3 ways
3-way version with diameter 40 flange for the connection of the control pressure gauge
2-way manifold
Double gauge valve to reduce operating costs on measuring systems and spare double valves with different nipples and fittings.
