Cast Steel Low Pressure Gate Valve is made up of cast iron body and is used to regulate low pressure liquid flows. The valve is a gate valve with gates of various types and shapes. The size and dimensions of the valves vary with the standards. The Cast Steel Pressure Gate Valve is made up of WCB, WC6, WC9, WCC, DF8, CF3, CF3M and other cast iron material types. The sizes of the valves vary from 2 inches to 48 inches. The pressure classes vary from 150lbs to 900lbs with pressure numbers varying from PN10 through PN150. The cast steel pressure gate valve class 150 is one of the lower classes which is suitable for low pressure applications up to 150lbs. the design standards of these valves vary as API 600, 6D, DIN 3352 and EN1984.

Cast Iron Parallel Disk Gate Valves
The face to face standards are ASME B16.10 and DIN 3202. The flange dimension standards of the valves vary as ASME B16.5 and B16.47. The cast steel pressure gate valve weight depends on the material grade, size, disc type and other criteria. The connection is made by flanged ends of the valve with the flanged end of the pipes. The cast steel pressure gate valves manufacturers in india produce these valves in all sizes, dimensions, material grades and pressure capacities. The applications include water management, oil and gas, power plant, petroleum and other low pressure applications.
