Niagara Pressure Sustaining Valve

Simple to use direct acting upstream pressure sustaining pilot valve

The Niagara Pressure Sustaining Valve is a Hydraulically operated, diaphragm

actuated control valve that sustains minimum present Upstream (back) pressure

and opens fully When line pressure is in excess of setting

General Features:

Line pressure Driven, Hydraulically controlled

Prioritizes pressure zones

Ultra-high flow capacity-Low pressure loss

Controls system fill-up

Opens fully upon Line pressure rise

Unitized Flexible super travel (FST) Diaphragm

and Guided Plug

Accurate and stable regulation with smooth closing

Engineered Plastic Valve with Industrial Grade design

Highly durable, chemical and cavitation resistant

No internal bolts and nuts

hYflow ‘Y’ Valve body with “Look Through” Design

Typical Application:

Line Fill-up Control Solutions

Line Emptying Prevention

Systems Subject to varying supply pressure

Infield Filters Backwash Pressure Sustaining

Energy Saving Irrigation Systems

Requires low opening and actuation pressure

Prevents diaphragm erosion and distortion

Simple in-Line Inspection and Service
