SH – Spirax Hills Bronze Sight Glass & Check Valve
Manufactured by Spirax Sarco, the SH sight check is a sight glass and check valve combination in one unit. A ball in the top of the flow tube is lifted off its seat by the fluid as it flows through the cylindrical window to the outlet connection. The ball movement makes the flow easy to see yet provides shut-off on reverse flow.

Sight & Check • Tubular Window Sight Glass
Size & Connections
15mm (1/2″) to 25mm (1″) • BSP Threaded (NPT on request)
Duty
Air • Oil • Water • Liquids compatible with materials
Materials
Bronze Body • Borosilicate Glass • Copper Discharge Tube • Stainless Steel Ball
Max Working Pressure
3.5 Bar
Temperature Range
0°C to 148°C
