Product ID: 05116777 – Gland / High-Pressure Gland (Check Valve Component)

Description:
This component is a gland, also known as a high-pressure gland or check valve gland, designed for waterjet intensifier pumps . It is a precision-machined, threaded cylindrical component that serves as a retaining and sealing housing within the high-pressure check valve assembly. The gland is typically threaded into the check valve body and secures the internal components of the valve, including the seat, poppet, spring, and poppet pin, while providing high-pressure sealing . This gland is designed for use with .875 inch (7/8") plunger intensifier systems operating at 60,000 PSI (approximately 4,137 bar) .

Applications:

• Used as a retaining gland within the high-pressure discharge and/or inlet check valve assemblies of waterjet intensifier pumps .

• Threaded into the check valve body to secure and retain internal valve components (seat, poppet, spring, poppet pin) in their proper positions .

• Suitable for ultra-high pressure waterjet systems operating at 60,000 PSI (approximately 4,137 bar), compatible with .875 inch plunger intensifiers and check valve repair kits .

Features:

• Constructed from high-strength, corrosion-resistant material (typically hardened stainless steel) to withstand extreme pressure cycling and exposure to high-pressure water .

• Precision-machined external threads for proper fit and sealing within the check valve body .

• Precision-machined internal bore and sealing surfaces (e.g., O-ring grooves) to accommodate internal valve components and provide leak-free sealing .

• Designed to be tightened to a specific torque value to ensure proper compression of internal components and prevent high-pressure leaks .

• Allows access to internal wear components (seat, poppet, spring, seals) for inspection and replacement without removing the entire check valve body from the system .

Maintenance:

• Inspection: During check valve overhaul, inspect the gland threads for signs of wear, galling, corrosion, or damage. Inspect the internal sealing surfaces and O-ring grooves for pitting, scoring, or wear .

• Replacement Criteria: Replace the gland if threads are damaged, if sealing surfaces are compromised, if cracks are detected, or if the gland shows signs of stress corrosion .

• Torque Compliance: When reinstalling, tighten the gland to the specific torque value listed in the equipment service manual. Over-tightening may damage threads or distort the gland; under-tightening may cause high-pressure leaks or improper seating of internal components .

• Thread Lubrication: Apply manufacturer-recommended high-pressure thread lubricant or anti-seize compound to the external threads during reassembly to prevent galling and ensure accurate torque application .

• Seal Replacement: Always replace all O-rings and seals associated with the gland (e.g., the O-ring on the gland) with each reassembly. Do not reuse old seals .

• Full Depressurization: Always fully depressurize the waterjet system and follow lockout/tagout procedures before removing the check valve assembly or unthreading the gland .

• Kit Replacement: This gland is commonly available as part of high-pressure check valve repair kits, which include the gland, seat, poppet, spring, poppet pin, and associated seals for a complete valve overhaul .
