Graco 15A839 Cylinder Valve – Product Overview

Compatible Systems

System / Model Type	Description
Graco Plural‑Component Pumps	Mix / dispense modules that require a cylinder valve for fluid pressure control
Graco Repair & Service Modules	Replacement in valve repair kits for fluid‑handling assemblies
Graco Metering & Valve Blocks	High‑pressure valve assemblies where accurate sealing and fluid control are needed

Product Description

The Graco 15A839 Cylinder Valve is a critical internal fluid‑control component designed for high-pressure systems. It houses the valve mechanism that regulates fluid movement by acting as a sealed chamber through which fluid is either admitted, held, or released as part of a controlled process.

Manufactured to precise tolerances, the 15A839 ensures consistent fluid handling, proper sealing under pressure, and reliable operation through repeated cycles. This part is engineered to maintain performance in demanding industrial environments where precise fluid control is essential.

Key Features

Precision-machined internal valve chamber for reliable fluid control
Robust construction to withstand high pressure and frequent cycling
Seals reliably to prevent leakage when the valve closes
Easy to integrate into valve repair and rebuild kits
Supports long-term serviceability and system regeneration

Installation & Maintenance Tips

Always depressurize the system before disassembling the valve assembly.
Inspect the valve chamber for scoring, wear, or corrosion before installing the 15A839.
Use correct torque when tightening associated components to maintain seal integrity.
Replace internal seals, O-rings, or other valve internals when rebuilding.
Cycle the valve after assembly to verify smooth operation and sealing before returning to service.
