Product ID: 49894199 – Pneumatic Valve Cylinder / Actuator Cylinder

Description:
This component is a pneumatic actuator cylinder designed for use in high-pressure waterjet cutting systems . It is a precision-engineered pneumatic control component that converts compressed air pressure into controlled linear mechanical motion to actuate key functions within the waterjet system . Specifically, this cylinder is used in the pneumatic on/off valve assembly (such as the VL10189553 60K Actuator Assembly) to control the start and stop of the cutting jet .

This actuator cylinder is configured as a normally open (NO) unit, meaning the valve remains open when no pneumatic pressure is applied . It is designed for 60,000 PSI (approximately 4,137 bar) waterjet systems and serves as a direct OEM replacement component .

Applications:

• Used to actuate the on/off valve (water switch) on waterjet cutting heads, controlling the precise starting and stopping of the high-pressure waterjet .

• Installed in pneumatic valve assemblies within waterjet intensifier pumps and cutting systems .

• Suitable for controlling dump valve operations and pressure switching functions in waterjet systems .

• Compatible with waterjet systems from major manufacturers including KMT, FLOW, OMAX, BFT, and WSI .

Features:

• Normally Open Configuration: Default state is open; pneumatic pressure is required to close the valve .

• High-Quality Construction: Manufactured from hardened stainless steel and high-strength aluminum alloy, providing excellent durability, corrosion resistance, and dimensional precision .

• Low-Friction Design: Internal components are fitted with high-performance seals and low-friction guides, delivering fast response, stable actuation, and long service life .

• Pneumatic Pressure Rating: Operates on standard compressed air supply up to 120 PSI (approximately 8.3 bar) .

• Lightweight: Product weight is approximately 1.289 lbs (0.585 kg) .

• OEM Compatibility: Cross-reference part numbers include BV401184 and 103070 .

Maintenance:

• Routine Inspection: Periodically inspect the cylinder body and external components for signs of wear, damage, corrosion, or air leakage.

• Seal Check: Inspect internal seals for wear or deterioration. Worn seals can cause air bypass, resulting in slow or incomplete valve actuation. Replace seals as needed.

• Functional Testing: Verify correct operation by observing if the cutting head valve opens and closes properly in response to the CNC control signal.

• Air Supply Quality: Ensure clean, dry, lubricated compressed air is supplied to the cylinder to prevent internal corrosion and seal degradation.

• Actuator Assembly Context: This part number is for the cylinder body only and does not include internal components. The complete actuator assembly may include additional components (e.g., VL10189553) .

• Full Depressurization: Before performing any maintenance on the pneumatic valve cylinder, completely shut off the compressed air supply to the machine and vent any residual air pressure in the system. Also fully depressurize the high-pressure water system and follow lockout/tagout procedures.

• Replacement Criteria: Replace the actuator cylinder if it fails to actuate despite correct air supply signal, if it exhibits external air leakage, if the piston is seized, or if visible damage is present.

• Compatibility Verification: Before installation, verify that the replacement cylinder matches the specific actuator assembly and waterjet system model (confirm cross-reference with BV401184 or 103070) .
