Product Name: Pressure Side Valve / Discharge Valve Assembly (Part No. CP022044/844)

Description:
This component is the pressure side valve, also known as a discharge check valve assembly, specifically designed for BFT waterjet intensifier pumps. As a complete assembly, it replaces the need for individual loose parts, serving as a drop-in unit for the high-pressure outlet circuit of the intensifier .

Its primary function is to control the one-way flow of pressurized water exiting the high-pressure cylinder. During the compression stroke, the valve opens to allow the ultra-high-pressure water to flow toward the cutting head. Between strokes, it closes instantly to prevent backflow, which is critical for maintaining system pressure and protecting internal components from dangerous pressure spikes . It is rated for continuous operation at up to 4,137 bar (approximately 60,000 PSI).

Applications:

Installed on the high-pressure outlet port of BFT waterjet intensifier pumps.
Controls the discharge of pressurized water from the cylinder to the high-pressure line leading to the cutting head.
Suitable for ultra-high pressure waterjet systems operating at 60,000 PSI (4,137 bar) and above.
Compatible with BFT, BHDT, WJS, Maximator Jet, and STM waterjet systems.

Features:

Complete Assembly: Unlike loose repair kits, this is a pre-assembled unit for faster, drop-in replacement.
Stainless Steel Construction: Provides excellent corrosion resistance and structural integrity under extreme pressure cycling.
High-Pressure Rating: Engineered for continuous operation at 4,137 bar (60,000+ PSI).
Critical Component: Directly responsible for maintaining cutting pressure and preventing backflow damage.
Direct OEM Replacement: Interchangeable with OEM part numbers MJ0040001, 1100012, and 1-15602.

Maintenance:

Failure Diagnosis (When to Replace):

Significant Pressure Drop: A drop in cutting performance often indicates the discharge valve is leaking or failing to seat properly .
System Pressure Fluctuations: Erratic intensifier cycling or pressure spikes can be caused by a stuck or worn pressure valve.
External Leakage: Water weeping from the valve body indicates internal seal failure.
Increased Pump Noise: Knocking or hammering sounds during the compression stroke often point to a faulty check valve .
Scheduled Preventive Maintenance: Replacing the discharge valve as a complete assembly during major overhauls prevents unplanned downtime.

Replacement and Inspection Guidelines:

Full Depressurization (Critical): Before any maintenance, shut down the pump, fully depressurize the high-pressure water system, and follow lockout/tagout procedures .
Drop-In Replacement: This part is designed to be removed and replaced as a single unit; do not attempt to disassemble the internal components.
Clean Installation: Thoroughly clean the mounting cavity in the manifold block before inserting the new valve.
Lubrication: Apply a thin film of clean hydraulic oil or high-pressure grease to the O-rings and sealing surfaces during installation .
Torque Compliance: Tighten the retaining nut or manifold bolts to the specific torque value listed in the equipment service manual to prevent damage.
Storage: Keep spare assemblies in clean, sealed packaging to prevent contamination of the internal sealing surfaces.
