Product ID: 05112768 – Seat, Flat Outlet Poppet (Check Valve Component)

Description:
This component is a high-pressure (HP) seat, specifically a flat outlet poppet seat, designed for the check valve assembly in waterjet intensifier pumps . It is a precision-machined, disc-shaped sealing component that serves as the stationary sealing surface for the outlet (discharge) poppet. The seat works in conjunction with the outlet poppet (e.g., Product ID 05116561) to create a leak-tight, one-way seal, controlling the flow of pressurized water from the intensifier cylinder to the outlet manifold.

This seat 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 1-11266, 10107902, 7800039, and WA1024 .

Applications:

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

• Installed in the check valve body or sealing head assembly, positioned between the intensifier cylinder and the outlet poppet

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

• Compatible with SL-V, SL-VI, Neoline, and other .875 plunger intensifier assemblies 

Features:

• Flat Seat Design: Engineered as a flat outlet poppet seat, providing reliable sealing under extreme pressure cycling 

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

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

• High-Strength Material: Manufactured from wear-resistant material to withstand repeated impact from the poppet and high-velocity water flow

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

• Weight: Approximately 0.03 kg 

Maintenance:

• Critical Wear Component: The seat is a consumable part. If the seat 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 seat sealing surface for pitting, erosion, cracking, or indentation caused by repeated poppet impact. Even minor surface damage can cause pressure loss

• Replacement Criteria: Replace the seat immediately if any surface damage is visible. A worn or damaged seat will prevent the check valve from sealing properly

• Water Quality Impact: If the seat requires replacement too frequently, investigate potential causes such as poor water quality (contaminants accelerating wear) or damage to the corresponding poppet or check valve body 

• Simultaneous Poppet Replacement: Always replace the corresponding outlet poppet simultaneously with the seat. Reusing a worn poppet with a new seat will compromise sealing and shorten seat life

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

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