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

Description:
This component is a high-pressure gland, specifically a gland nut for the check valve assembly in waterjet intensifier pumps . It is a precision-machined, threaded cylindrical nut that serves as a retaining and sealing component within the high-pressure check valve assembly. The gland is threaded into the check valve body or sealing head assembly and secures the internal valve components, including the seat, poppet, spring, and poppet retainer, while providing high-pressure sealing .

This gland is designed for .875 inch (7/8") plunger intensifier systems and is rated for 60,000 PSI (approximately 4,137 bar) operation . Alternative or cross-reference part numbers include 1-11267 and WK000242 .

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 or sealing head assembly to secure and retain internal valve components (seat, poppet, spring, poppet retainer) 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 such as SL-IV, SL-V, SL-VI, Neoline, and Classic series pumps

Features:

• High-Strength Construction: Manufactured from hardened stainless steel or high-strength alloy steel, providing exceptional resistance to pressure fatigue and corrosion

• Precision-Machined Threads: Features precision-cut external threads for proper fit and sealing within the check valve body or sealing head assembly

• Internal Sealing Surfaces: Precision-machined internal bore and sealing surfaces (including O-ring grooves) to accommodate internal valve components and provide leak-free sealing

• Consumable Component: While durable, the gland is subject to wear on its threads and sealing surfaces and should be inspected during check valve maintenance

• OEM Compatibility: Direct replacement part for KMT and other major waterjet systems

• Weight: Approximately 0.05 kg

Maintenance:

• Inspection: During check valve overhaul or sealing head service, 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 or deformation

• 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 Availability: This gland is commonly available as part of high-pressure check valve repair kits (e.g., WK000242, 80074057, 20489495), which include the gland, seat, poppet, spring, poppet retainer, and associated seals for a complete valve overhaul
