XLC 312/412 PN 25

The CSA model XLC 312/412 is a globe pattern hydraulically operated automatic control valve that reduces and stabilizes the downstream pressure to a constant value, regardless of variation in demands, maintaining at the same time the upstream pressure within a minimum value.

Product features
• Body and cover in ductile cast iron GJS 450-10.
• Internals in ductile cast iron GJS 450-10 and stainless steel.
• Position indicator in stainless steel.
• Circuitry in stainless steel.
• Unit flow regulator device, needle valves and flow stabilizers in stainless steel.
• Seat in stainless steel.
• Painting with fluidized bed technology RAL 5005.

Applications
• Installed on the main line to prioritize elevated pressure zones maintaining a downstream pressure to a pre-set value.
• At the pumps to prevent excessive flow and ensuring at the same time the water supply within pressure values acceptable for the system.
• Located between two pressure zones to compensate the lower one with exceeding values at night, and throttling with peak hours to maintain the upper one to the desired value.

Standard and connections
• Design and testing according to EN 1074.
• Flanges size from DN 50 to DN 400 mm, higher on request.
• Flanges standard EN 1092/2, different on request.

Working conditions
• Pressure range: 10-16-25 bar.
• Minimum working pressure: 0.7 bar acting on the pilot.
• Treated water maximum 70°C, higher temperature on request.
