Graco 15G905 Valve Plate Retainer

High‑Precision Retainer Valve Plate – Graco 15G905

Product Overview

The Graco 15G905 Retainer Valve Plate is a critical component designed to securely fasten and position the valve plate assembly in high‑performance fluid delivery systems. Engineered to maintain accurate alignment and sealing integrity under high‑pressure and high‑cycle conditions, it supports reliable pump operation and prolongs the life of the overall system.

Key Features

• Precision‑machined retainer body ensures flat, consistent seating of the valve plate
• Durable alloy construction for long term resistance to fatigue and corrosion
• OEM‑quality fit that maintains factory alignment and performance standards
• Maintains sealing integrity by holding the valve plate firmly against the gasket and bore
• Supports high‑cycle operations in demanding pump or spray system environments

Construction & Materials

This retainer valve plate is constructed from robust alloy steel engineered to withstand repeated compression, vibration and fluid exposure. Its mounting faces are machined to tight tolerances to ensure the valve plate remains properly seated and aligned. Surface treatments provide additional protection against corrosion and extend service intervals.

Performance & Compatibility

The 15G905 is intended for inclusion in systems where the valve plate needs a reliable retainer to prevent movement, maintain pressure seals and ensure consistent fluid paths. By keeping the valve plate properly anchored, it reduces the risk of leakage, misalignment, and premature component wear—thus helping maintain optimal pump efficiency and uptime.

Installation & Maintenance

During installation, ensure the mating surfaces are clean and free of damage. Position the valve plate correctly, then install the 15G905 retainer and torque mounting screws to manufacturer specified values. During regular maintenance, inspect the retainer for signs of wear, cracking or corrosion—especially after high‑cycle usage—and replace it if any integrity issue is observed to maintain reliable performance.

Why It Matters

In high‑demand fluid systems, failures or looseness in the valve plate assembly can lead to major performance losses, increased maintenance costs, and downtime. The Graco 15G905 Retainer Valve Plate plays a crucial role by securely anchoring this critical component—helping preserve system alignment, reduce wear, and ensure the longevity of your equipment.
