LP Check Valve Poppet SP-73-2 Waterjet Pump Parts In Stock
LP Check Valve Poppet SP-73-2 Waterjet Pump Parts In Stock
The SP-73-2 is the low-pressure (LP) Check Valve Poppet used in Waterjet Intensifier-Assembly-80072333-Good-Quality-Water-Jet-Parts-In-Stock-p.html target='_blank'>Intensifier pumps, ensuring one-way flow of hydraulic fluid at low‐pressure stages of the pump cycle. Manufactured to OEM specifications for systems, it interfaces with the LP check valve housing (SP-72-7) and Spring-F1000401-220-BFT-Abrasive-Water-Jet-Parts-In-Stock-p.html target='_blank'>Spring (500-12-0040) to maintain proper pressure balance and prevent backflow when the intensifier Piston reverses direction.
Specifications
Material:Hardened stainless sTeel poppet (proprietary alloy)
Pressure Stage:Low-pressure check (intensifier return stroke)
Operating Pressure:Up to ~5–10 ksi (LP stage of dual-stage intensifier)
Compatibility:Techni Gen 2 and Gen 4 Intensifier Pumps (all models)
Weight:~0.02 kg (approximate)
Installation & Maintenance
Depressurize & Drain: Fully isolate the pump and relieve hydraulic pressure.
Access Valve Housing: Remove the intensifier end plate to expose the LP check valve housing (SP-72-7)
Disassemble Housing: Extract the LP spring (500-12-0040) and gently press out the old poppet (SP-73-2) from the housing bore
Inspect & Clean: Clean the housing and spring seat. Inspect bore for scoring; polish or replace if out of tolerance.
Install New Poppet: Place the new SP-73-2 poppet into the housing, reinsert the LP spring, and reassemble per torque specifications.
Test Operation: Repressurize the system at low pressure, cycle the intensifier, and verify one-way flow; then ramp to full pressure and check for leaks.
