05116751 Poppet Retainer
Product ID: 05116751 – Poppet Retainer / Poppet Pin (Check Valve Component)
Description:
This component is a poppet retainer, also referred to as a poppet pin or spring guide, designed for the high-pressure check valve assembly within waterjet intensifier pumps . It is a small, precision-machined cylindrical pin that serves as both a spring guide and a retaining element, positioning the compression spring and maintaining alignment with the outlet poppet during valve operation .
The poppet retainer is installed between the discharge poppet (outlet poppet) and the compression spring, ensuring that the spring remains properly centered and that the poppet moves axially without binding . This component is a critical part of the sealing head assembly and is included as a standard component in high-pressure check valve repair kits .
This part is designed for .875 inch (7/8") plunger intensifier systems and is rated for 60,000–90,000 PSI (approximately 4,137–6,200 bar) operation . Alternative or cross-reference part numbers include WA1025, and it is commonly listed as item #7 in sealing head assembly diagrams . The component has an approximate weight of 0.001 kg .
Applications:
Used as a spring guide and poppet retainer within the discharge (outlet) check valve assembly of waterjet intensifier pumps
Installed between the discharge poppet (Product ID 05116561) and the compression spring (Product ID 05147863) to maintain spring centering and poppet alignment
Suitable for ultra-high pressure waterjet systems operating at 60,000–90,000 PSI (approximately 4,137–6,200 bar)
Compatible with KMT Streamline SL-IV, SL-V, SL-VI, PRO-III, Neoline, and other .875 inch plunger intensifier assemblies
Compatible with FLOW, OMAX, BFT, WSI, and other OEM waterjet systems
Features:
Precision-Machined Cylindrical Pin: Small, accurately machined component ensuring proper spring alignment and smooth poppet movement
Spring Guide Function: Centers the compression spring to prevent lateral movement and ensure consistent spring force application
Poppet Alignment: Maintains axial alignment between the discharge poppet and valve seat for reliable sealing
Consumable Component: The poppet retainer is a wear component that should be replaced as part of regular check valve maintenance
High-Pressure Rating: Engineered for continuous operation at 60,000–90,000 PSI (4,137–6,200 bar)
OEM Compatibility: Direct replacement part for KMT and other major waterjet systems
Corrosion-Resistant Surface: Silver finish with anti-corrosion treatment for durability in waterjet environments
Maintenance:
Critical Wear Component: The poppet retainer is a consumable part. Wear or deformation can cause spring misalignment, leading to poor valve sealing and pressure loss
Inspection: During check valve or intensifier overhaul, inspect the poppet retainer for signs of wear, bending, scoring, cracking, or corrosion. The small size of this component makes it susceptible to damage from debris
Replacement Criteria: Replace the poppet retainer if any visible wear, deformation, or damage is detected. A worn or bent retainer can cause the compression spring to lose alignment, leading to incomplete valve closure
Set Replacement (Recommended): When servicing the discharge check valve, it is recommended to replace the poppet retainer simultaneously with the discharge poppet (05116561), valve seat (05112768), and compression spring (05147863) as a complete set
Proper Assembly: During reassembly, ensure the poppet retainer is correctly inserted between the spring and the poppet. The retainer centers the spring and should move freely without binding
Full Depressurization: Always fully depressurize the waterjet system and follow lockout/tagout procedures before removing the check valve assembly or replacing the poppet retainer
Kit Availability: This poppet retainer is commonly available as part of check valve repair kits (e.g., 20489495, 80074057, WK000377), which include the retainer, poppet, seat, spring, and other required components for a complete valve overhaul
