Product ID: 05116561 – HP Poppet / Outlet Poppet (Check Valve Component)

Description:
This component is a high-pressure (HP) poppet, also known as an outlet poppet, discharge poppet, or seal head poppet . It is a precision-machined, stem-like sealing component that serves as the moving element within the high-pressure check valve assembly of waterjet intensifier pumps. The poppet works in conjunction with the HP seat (Product ID 05112768) to create a leak-tight, one-way seal, controlling the flow of pressurized water from the intensifier cylinder to the outlet manifold . This poppet is specifically designed for the outlet (discharge) side of the check valve and is rated for ultra-high pressure operation.

This component is designed for .875 inch (7/8") plunger intensifier systems and is typically rated for 60,000 PSI (approximately 4,137 bar) operation . Alternative or cross-reference part numbers include 1-11265, 10107901, 0511656-1, and 05016561 .

Applications:

• Used as the outlet (discharge) check valve poppet within the high-pressure check valve assembly of waterjet intensifier pumps 

• Installed in the check valve body or sealing head assembly, positioned against the HP seat, sealing under pressure to prevent reverse water flow from the outlet line back into the intensifier cylinder 

• Suitable for ultra-high pressure waterjet systems operating at 60,000 PSI (approximately 4,137 bar) and higher

• Compatible with .875 inch plunger intensifiers such as Neoline, SL-IV, SL-V, and Classic series pumps 

• Commonly used in KMT, AccuStream, and other OEM waterjet systems 

Features:

• Flat Poppet Design: Engineered as a flat outlet poppet for reliable sealing under extreme pressure cycling 

• Precision-Ground Sealing Surface: Machined to exact specifications for leak-tight shut-off when mated with the corresponding HP seat

• Consumable Component: The poppet is a high-wear consumable part designed to protect the more expensive check valve body 

• High-Strength Material: Constructed from wear-resistant, hardened stainless steel or specialized alloy to withstand repeated impact against the valve seat and high-velocity water flow

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

Maintenance:

• Critical Wear Component: The HP poppet is a high-wear consumable part. If the poppet sealing surface is damaged or worn, the machine will experience pressure drop or inability to maintain rated cutting pressure 

• Inspection: During check valve or intensifier overhaul, inspect the poppet sealing surface for pitting, erosion, cracking, indentation, or mushrooming caused by repeated impact against the seat. Even minor surface damage can cause pressure loss

• Replacement Criteria: Replace the HP poppet immediately if any surface damage is visible. A worn or damaged poppet will prevent the check valve from sealing properly, leading to pressure drop, reduced cutting performance, and increased pump cycle times 

• Simultaneous Seat Replacement: Always replace the corresponding HP seat (05112768) simultaneously with the poppet. Reusing a worn seat with a new poppet (or vice versa) will compromise sealing and shorten the life of both components 

• Water Quality Impact: Poor water quality (contaminants, hardness) accelerates wear on both the poppet and seat. If these components require replacement too frequently, investigate and improve water filtration/treatment

• Full Depressurization: Always fully depressurize the waterjet system and follow lockout/tagout procedures before removing the check valve assembly or replacing the HP poppet

• Kit Availability: This poppet is commonly available as part of check valve repair kits (e.g., 80074057, 20489495, WK000377), which include the poppet, seat, spring, and other required components for a complete valve overhaul
