Globe Valve

Derval Globe valves are ideal for shut off as well as for throttling service. Their flow characteristics permit accurate and repeatable flow control. However, caution must be exercised to avoid extremely close throttling when pressure drop exceeds 20%. This creates excessive noise, vibration and possible damage to valves and piping. They are widely used for water, saturated steam, air, gas, oil and crude oil products. Operating parameters are in accordance with ASME B16.34 standard.

Derval Globe valve can be installed into pipeline in any position, however the best location for a perfect leak proof is horizontal with the stem moving vertically (handwheel up). The high-quality Derval valves are installed in a large variety of services in the Oil & Gas field, Chemical and Petrochemical industry, in On-shore and Off-shore drilling/refining, Power Generation, Water and Wastewater Treatment industries.
