Product Name: 2-Way Angle Valve, 1/4" – Part No. 10079002

Description:
This component is a 2-way angle valve, specifically designed for 1/4 inch high-pressure waterjet cutting systems . The “2-way” designation indicates it has two ports (one inlet, one outlet), providing on/off control of the high-pressure water flow. The “angle” configuration features a 90-degree flow path, making it ideal for installations where space is constrained or where a directional change is required .

According to manufacturer documentation, this valve is rated for continuous operation at 60,000 PSI (approximately 4,137 bar) . Constructed from high-strength 316 stainless steel, it is engineered to withstand the extreme pressure cycling, vibration, and erosive conditions inherent in waterjet cutting operations .

This valve is an OEM-equivalent replacement part, with multiple cross-reference part numbers including AccuStream 1-13167-60-4, Flow A-0787-1, KMT 10079002, and WSI FT60VM4072 . The product weight is approximately 0.838 kg (1.85 lbs) . It is compatible with major waterjet systems including KMT, FLOW, BFT, WSI, and APW .

Applications:

• Provides on/off control of high-pressure water flow in waterjet cutting systems, allowing operators to start, stop, or redirect pressure safely 

• Installed between the intensifier pump outlet and the cutting head assembly for main flow control

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

• Used in high-pressure manifolds, accumulator systems, and cutting head supply lines

• Commonly used for pressure isolation, safety shutoff, and directional flow control in both cutting and pumping circuits 

• Compatible with KMT, FLOW, AccuStream, H2O Jet, OMAX, BFT, WSI, and other standard waterjet systems 

Features:

• 2-Way, 90° Angle Configuration: Provides on/off flow control with a 90-degree directional change for space-efficient routing in tight installations 

• 1/4 Inch Connection Size: Standard size for flexible high-pressure waterjet plumbing and motion axes

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

• 316 Stainless Steel Construction: Provides excellent corrosion resistance and structural integrity under extreme pressure cycling 

• Precision-Machined Sealing Surfaces: Ensures leak-tight shut-off and smooth valve operation. Internal components including stem, seat, and sealing surfaces are precision-ground and polished for long-lasting sealing integrity 

• Standard Cone-and-Thread Connections: Compatible with standard 1/4″ HP fittings, gland nuts, and coned inserts

• Direct OEM Replacement: Interchangeable with AccuStream 1-13167-60-4, Flow A-0787-1, KMT 10079002, WSI FT60VM4072 

• Weight: Approximately 0.838 kg (1.85 lbs) 

• Manual Operation: Manually operated hand valve for reliable flow control 

Maintenance:

Failure Diagnosis (When to Replace):

• External Water Leakage: Visible water weeping from the valve body or stem indicates seal failure, requiring immediate valve replacement or seal overhaul

• Thread Damage: Stripped, galled, or corroded thread ports prevent proper tightening and will cause high-pressure leaks

• Cone Seat Damage: Nicks, galling, or pitting on the 60-degree cone sealing surfaces will compromise the seal

• Stem Seal Failure: If the valve leaks from the stem area during operation, internal stem seals have failed

• Difficult Operation: If the valve handle requires excessive force or feels gritty when turning, internal components may be damaged or contaminated

• Cracked or Deformed Body: Any visible cracking or distortion of the stainless steel valve body warrants immediate replacement

• Scheduled Preventive Maintenance: Develop a routine for leak-checking high-pressure fittings and valves at the beginning of each shift; repair any leaks as soon as they are discovered

Inspection and Replacement Guidelines:

• Full Depressurization (Critical): Before any maintenance, place the main electrical disconnect in the OFF position, bleed down all high-pressure lines, and follow lockout/tagout procedures. Never service a pressurized HP line

• Leak Detection: Leaks not visible to the naked eye can often be discovered by feeling the temperature of components — if a connection feels warmer than normal, internal leakage may be occurring

• Port Inspection: Before installation, thoroughly inspect both port threads and cone seats for nicks, galling, or deformation. Examine the valve body for cracks or corrosion

• Component Replacement Practice: When disassembling a high-pressure joint, it is standard practice to replace the cone, gland, and collar if they show signs of wear

• Thread Lubrication: Apply a thin, even layer of high-pressure anti-seize lubricant (e.g., “Silver Grade” or “Blue Goop”) to the male threads of the mating gland nuts only. Do not apply lubricant to the cone sealing surfaces

• Two-Wrench Method (Critical): When tightening or loosening connections, use two appropriately sized wrenches—one to counter-hold the valve body and one to tighten the gland nut—to prevent twisting stress on the assembly

• Torque Compliance: Tighten all connections to the specific torque values listed in the equipment service manual for 1/4" HP connections using a calibrated torque wrench. Over-tightening can damage threads or cone seats; under-tightening will cause high-pressure leaks

• Clean Area Maintenance: Perform valve rebuilds in a designated clean area to prevent contamination of replacement parts with abrasive particles; wear disposable gloves to prevent natural oils from being introduced to seal materials

• Replace if Damaged: Replace the valve immediately if threads are damaged, cone seats are pitted or deformed, cracks are visible, stem seals are leaking, or persistent leakage occurs despite correct installation

• Storage: Store spare valves in a clean, dry environment to protect precision threads and sealing surfaces from damage before use
