Polyhydron CI20SA Pilot Operated Check Valve
Discription
Pilot Operated Check valve models CI **** Allow Free Flow In The Direction From Port A To Port B And Offer Leak Free Closure In Opposite Direction.
Reverse Flow Can Be Achieved By Applying Pilot Pressure To Its Port X.
The Pilot Pressure Required At Port X To Achieve Reverse Flow From Its Closed Position Can Be Calculated Using The Formulae Given In The Technical Specifications.
Generally, To Achieve Smooth Decompression Of Oil In A Hydraulic Actuator Prior To Reverse Flow, It Is Essential To Keep The Pilot Pressure As Close To The Calculated Value As Possible And The Flow controlled.

Formulae For Pilot Pressure Required At Port X Open The Valve For Flow From Port B To Port A
| To open Decompression Poppet | Type A | Type B |
| >PA + PB/16 + 0.5 | >PA/1.5 + PB/4 + 2 | |
| To Open The Main Poppet | >PA/2 + PB/2 + 0.5 | >2PB - PA + 2 |
|
Where, PA = Pressure at Port A And PB = Pressure At Port B , When The Flow Occurs.
