65 Topworks 65 sq. in. diaphragm P. O. service Extends 1” HPMV with ½” inner valve to 4000# W.P. Extends SMS valve to 4000# W.P. Available for 1”, 2” and non-freeze HPMV Wide spring adjustment range
9
Manual Valve Positioner Used as a limit for valve stem travel Used to manually open the valve on unit start-up Each revolution of the handle moves the stem 1/16” ¾” max. stem travel
10
Pneumatic Valve Positioner Maintains stem position through changes in force on stem Provides repeatable stem placement
12
Soft Seat 15/16” port in 1” valve 1-1/2” port in 2” valve Maximum pressure drop: 300 psi On / Off service only
13
Improving Service of HPMV’s Size Valve Properly. Valve should operate between 50% and 80% of its capacity Use quick opening trim in erosive service. Use Carbide or Zirconia trim in highly erosive service. Use Equal Percentage trim for controlling pressure or flow rate.
