Repair Kit for GS40/GS40GI Control Valves

Repair Parts for AR/Hypro GS40 Valves

The 9910-KIT1757 repair kit (also AR1757) is designed to replace worn, damaged, or broken components on your Hypro or AR GS40GI control valves. GS40GI pressure regulator units are often used with Hypro and AR D30 (AR30) and D50 (AR50) diaphragm pumps to regulate the output pressure while in operation. Over the course of long-term operation, some valve components will wear out. For example, if there is a lack of pressure, it is possible that the gasket seal, relief valve poppet retainer, or tension springs need replacing. The GS40GI repair kit can correct inconsistent flow rates associated with pressure loss and includes the necessary parts to fix most issues with control unit performance.

The 9910-KIT1757 includes:
  • (1) 9910-320433 – Relief Valve Poppet Retainer
  • (1) 9910-320511 – Gasket Seal O-Ring
  • (1) 9910-390140 – Tension Spring Guide
  • (1) 9910-320420 – Tension Spring
  • (1) 9910-450110 – Spring Holder
  • (1) 9910-110122 – Relief Valve Seat
