Product Name: Water On/Off Valve Body

Description:
This component is the main valve body of a pneumatic on/off valve (water switch) for high-pressure waterjet cutting systems. It is a precision-machined stainless steel or hardened alloy block that serves as the central fluid passage housing for controlling the start and stop of the ultra-high-pressure waterjet. The valve body contains internal flow passages, precision-machined sealing surfaces, and threaded ports for high-pressure connections. It is rated for continuous operation at 60,000 PSI (approximately 4,137 bar) and is designed to withstand extreme pressure cycling without deformation.

Applications:

• Used as the main housing for the pneumatic on/off valve assembly in waterjet cutting systems

• Installed between the high-pressure pump outlet and the cutting head to control water flow

• Suitable for ultra-high pressure waterjet systems operating at 60,000–90,000 PSI (approximately 4,137–6,200 bar)

Features:

• High-Pressure Rating: Engineered for continuous operation at 60,000 PSI (4,137 bar)

• Corrosion-Resistant Construction: Manufactured from stainless steel or hardened alloy to withstand harsh waterjet environments

• Precision-Machined Internal Passages: Features cross-drilled flow ports for efficient water direction with minimal pressure loss

• Standard High-Pressure Threads: Equipped with industry-standard HP threads for secure connection to glands, fittings, and cutting head components

• Leak-Tight Sealing Surfaces: Precision-machined seats ensure proper sealing with valve stem and seal assemblies

Maintenance:

• Regular Inspection: Inspect the valve body for signs of cracking, corrosion, pitting, or erosion. Pay particular attention to internal flow passages and sealing surfaces

• Thread Inspection: Check all threaded ports for wear, galling, or deformation. Damaged threads can cause high-pressure leaks

• Internal Cleaning: Clean internal flow passages thoroughly using low-pressure water and soft brushes. Remove all debris, mineral deposits, or old seal residue. Do not use metal tools that could scratch sealing surfaces

• Seal Replacement: Always replace all O-rings, backup rings, and seal assemblies when servicing the valve body

• Full Depressurization: Always fully depressurize the waterjet system and follow lockout/tagout procedures before removing or servicing the valve body

• Torque Compliance: Tighten all connections to the specific torque values listed in the equipment service manual

• Thread Lubrication: Apply high-pressure thread lubricant or anti-seize compound to threads during reassembly to prevent galling

• Replacement Criteria: Replace the valve body if cracks, severe corrosion, internal erosion, or thread damage is detected
