Product Name: 2-Way Angle Valve, 3/8" – Part No. 10078749

Description:
This component is a 2-way angle valve, specifically designed for 3/8 inch high-pressure waterjet systems . According to manufacturer parts documentation, this valve is listed as Item 2 in Table 12-54 (High Pressure Fitting and Valve Assemblies) and is rated for 60,000 PSI (approximately 4,137 bar) operation .

The valve features a 90-degree flow path (angle design), which allows for efficient routing of high-pressure water lines in space-constrained areas around the intensifier pump, manifold, or cutting head assembly . The "2-way" designation indicates it has two ports (one inlet, one outlet), providing on/off control of the high-pressure water flow.

Constructed from high-strength 316 stainless steel, this valve is engineered to withstand the extreme pressure cycling, vibration, and erosive conditions inherent in waterjet cutting operations . The valve utilizes industry-standard 3/8 inch cone-and-thread (FT) connections, making it fully compatible with standard high-pressure fittings, gland nuts, and coned inserts .

This valve is an OEM-equivalent replacement part, cross-referenced with AccuStream part number 1-13167-60-6 and KMT part number 49864440 . 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
Installed between the intensifier pump outlet and the cutting head assembly
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
Compatible with KMT, FLOW, BFT, WSI, APW, 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
3/8 Inch Connection Size: Industry-standard size for medium-to-high flow waterjet plumbing
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
Standard Cone-and-Thread Connections: Compatible with standard 3/8″ HP fittings, gland nuts, and coned inserts
Direct OEM Replacement: Interchangeable with AccuStream 1-13167-60-6, KMT 49864440, and H2O Jet 400072-2-2-90

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
Cracked or Deformed Body: Any visible cracking or distortion of the stainless steel valve body warrants immediate replacement
Scheduled Preventive Maintenance: Inspect valves during major pump overhauls (typically every 4,500-5,000 operating hours) and replace if any wear or damage is detected

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
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 3/8" HP connections using a calibrated torque wrench. Over-tightening can damage threads or cone seats; under-tightening will cause high-pressure leaks
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
