Crane DM931 Variable Orifice Double Regulating Valve

Crane DM931 ductile iron variable orifice double regulating valve. The double regulating feature allows the valve to be used for isolation and the be reopened to its pre-set position to maintain required flow rate.

• Ductile iron body
• PN16 flanged ends
• Y-pattern globe valves supplied with two pressure test points to provide flow measurement, regulation and isolation
• Valves conform to requirements of BS 7350: 1990 and ends are flanged to BS EN 1092-2 (formerly BS 4504)
• Primarily used in injection or other circuits requiring a double regulating valve for system balancing
• Accuracy of flow measurement is ±10% at the full open position of the valve. Some reduction in accuracy occurs at partial openings of the valve in accordance with BS 7350
