The GRACO 236591 is a diaphragm plate assembly designed for use in GRACO fluid pressure regulators. It is a critical component that supports the diaphragm and ensures proper sealing and pressure regulation within the regulator assembly. The part is typically constructed from durable materials suitable for industrial environments, though specific material is not always detailed in product listings. Its primary function is to maintain the integrity and performance of the regulator by securely holding the diaphragm and associated gaskets in place.

Key Features:

• Diaphragm Plate Assembly
• 236591
• Designed for use with GRACO fluid pressure regulators (e.g., models referenced in GRACO manual 308325E)
• Supports diaphragm and gasket for reliable sealing
• Engineered for ease of maintenance and replacement
• Robust construction for industrial duty cycles

Applications:
Used in GRACO fluid pressure regulators for controlling and maintaining consistent fluid pressure in lubrication, spray, and fluid handling systems. Suitable for industrial, mining, and agricultural equipment maintenance.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the regulator assembly. Non-genuine parts may compromise system integrity and void warranties.
• Assemble the diaphragm plate with the gasket and diaphragm, ensuring the PTFE side of the diaphragm faces the plate.
• Secure components with the jam nut, torquing to 28–32 ft-lb (38–43 N.m).
• Install the assembled parts in the regulator housing with the stem oriented toward the seat.
• Follow the specified tightening sequence and torque values for all fasteners to ensure proper sealing and prevent damage to plastic threads.
• Use thread sealant on air line fittings and torque to 140–160 in-lb (16–18 N.m).
• Torque hex head screws evenly in the sequence shown in the manual, compensating for diaphragm relaxation.
