Product Name: Ball Valve Assembly (PN 05070750)

Description:
The Ball Valve Assembly is a quarter-turn rotary control valve used to isolate or regulate the flow of hydraulic fluid or water within a waterjet cutting system. It utilizes a spherical ball with a central bore to control media passage . When the handle is perpendicular to the flow, the valve is closed; when parallel, it is fully open. This specific assembly is built from high-strength, corrosion-resistant materials (e.g., plated carbon steel or stainless steel) to withstand the high pressures and harsh operating environment of waterjet equipment .

Applications:

• Isolation of hydraulic fluid flow in the reservoir assembly, tank drain, or pump intake lines.

• Blocking or allowing flow of water to specific sections of the system.

• Used as a shut-off valve for maintenance, servicing, or emergency isolation.

• Listed as Item 9 in the official parts diagram for the Hydraulic Reservoir Assembly (P/N 72152878), where it is used in a quantity of 1 per assembly .

• Compatible with KMT, AccuStream, H2O Jet, and other standard waterjet hydraulic systems.

Features:

• Quarter-Turn Operation: Provides quick, positive shut-off with a simple 90° rotation of the handle.

• Full Bore Design: When fully open, the ball bore matches the pipe diameter, minimizing pressure drop across the valve .

• Bidirectional Sealing: Capable of sealing against pressure from either direction.

• Low Torque: The smooth ball surface and PTFE or reinforced seats provide reliable sealing with low operating torque.

• Durable Construction: Made from high-strength materials with protective plating to resist corrosion from water and hydraulic fluid.

Maintenance:

• Leak Detection (Stem/Handle): If fluid leaks from around the valve stem while the valve is open or closed, the stem packing or O-ring has failed, and the valve requires replacement.

• Leak Detection (Seat): If the valve fails to stop flow when fully closed (i.e., fluid continues to pass in the "off" position), the internal ball or the seats are worn, and the valve must be replaced.

• Operational Check: Operate the valve through its full range periodically to prevent it from sticking. If the handle feels rough or seizes, the internal components have failed.

• Full Depressurization (Critical): Before any maintenance or disassembly, fully depressurize the hydraulic system and high-pressure water circuit, and follow lockout/tagout procedures.

• Do Not Force: If the valve is stuck, do not use excessive force (e.g., with a wrench) on the handle, as this will damage the internal ball or stem.

• Replacement Criteria: This valve is considered a sealed, non-serviceable component. If it is leaking or sticking, it must be replaced as a complete assembly .

• Clean Mounting: When replacing, ensure the mating pipe threads or flanges are clean and free of old sealant.
