The 700H high side piston type valve is operated by a 275AP pilot float valve. The pilot float valve follows the rise and fall of liquid in the vessel or drain to which it is attached. The combination of valves results in a modulating control. The 700H valves are flanged, with a manual lifting stem (with seal cap for halocarbons). The metering plug and spring are selected for the operating conditions. Teflon seat discs are standard, and are replaceable. The pilot float is available with a cast steel chamber, or a 6″ x 24″ welded chamber with Phillips Level Eye.
These valves are applicable for feeding from the condenser to an evaporator, or from multiple condensers to a controlled pressure receiver or flash cooler. They can also be used on heat reclaim exchangers to drain condensate.
700H Valve Series includes 700JRH, 700XH, 700AXH and 700BXH
