FEATURES:
Compactdesign
O Ring sealed seat
Valve travel indicator
Field reversible topworks
Teflon packed stuffing box
TOPWORKS:
Standard topworks have an effective diaphragm area of
approximately30 square inches for 1"and 65 square inches for 2"control valves.

SPRINGS:
The 1"HPCVsprings are available for diaphragm pressures of 10.20,and 30 psig
The2"HPCV springs are available for diaphragm pressures
of 15,20,and 30 psig.
Unless otherwise specified,all 1"HPCV′s with 1/2"INNER
VALVES get 30 psig spring others get 20 psig.spring,all 2" HPCV′s will be furnished with springs as follows 2000psig.W.P. valves,20Ib.springs and 4000 psig.W.P.valves,30 Ib.springs.
Top Adjusting Screwmaybe adjusted tovary the spring ten sion slightly;this affects pressure required to actuate valve.
