W.E. Anderson's
Flanged Hi-Flow™ Control Valves incorporate the
same versatility as our threaded, top-guided globe control
valves. Designed for precise process control of pressure,
temperature, flow and level, these valves conform to the
requirements of Class 125 or Class 250 in Iron, or Class
150 and 300 in Bronze and Stainless Steel. Standard models
incorporate push-to-close action and linear flow characteristics.
Optional push-to-open, or equal percent flow characteristics
are also available. High flow capacities and superior rangeability
enable the Hi-Flow™ control valve to be used for a wide
range of process control applications.
Heavy-duty Hi-Flow™ control valves are ruggedly
constructed of the highest quality materials, precision
machined and performance tested to assure years of trouble-free
service. Available with Bronze, Iron, or Stainless Steel
body, trim is 316SS with all welded plug construction to
provide superior durability and corrosion resistance. Standard
packing consists of spring loaded PTFE V-ring and wiper
to minimize friction without leakage at high operating pressures.
Inverted V-ring construction for vacuum service; double
opposing V-ring construction for alternating pressure/vacuum
service; and graphite packing with or without built in lubricator
are also readily available.
