XJF Accumulator Shut-off Valve

I. Product Introduction

The XJF Accumulator Shut-off Valve is developed and manufactured with reference to overseas industry technical data. The valve core adopts a hydraulic balance cone valve structure, specially designed for accumulator disassembly and maintenance. The valve body features a dedicated oil drain port, and can be used as a replacement for imported accumulator shut-off valves, achieving domestic substitution. The product features effortless opening and closing, compact structural layout, small overall size, light weight, and stable operating conditions, suitable for various hydraulic energy storage systems.

III. Core Features

1. Optimized Valve Core Structure: Adopts hydraulic balance cone valve main core with balanced opening/closing forces, requiring minimal operating force for valve opening; both manual and tool-assisted operation are more effortless and convenient;

2. Dedicated Maintenance Structure: The valve body features a dedicated oil drain port designed specifically for accumulator disassembly, allowing pre-draining of internal medium pressure for safe removal of accumulator valve components;

3. Domestic Substitution Compatibility: Benchmarked against imported shut-off valve structural dimensions and pressure-bearing performance with interchangeable interface dimensions, allowing direct replacement of imported valves for existing imported hydraulic unit upgrades;

4. Lightweight Design: Compact overall structure occupying minimal pipeline installation space, with low overall weight, suitable for installation in confined hydraulic stations and enclosed cabinet pipelines;

5. Multi-Medium Compatibility: Compatible with mineral hydraulic oil, water-glycol, and emulsion hydraulic transmission media, suitable for various corrosive and multi-category hydraulic oil circuit applications;

6. Stable High/Low Temperature Performance: Suitable for wide temperature range from -15°C to 65°C, providing stable performance in both seasonal workshop conditions and low-temperature outdoor environments.

IV. Comprehensive Advantages

1. Strong Replacement Compatibility: Dimensions, pressure rating, and interfaces benchmarked against imported models; domestic replacement of imported valves can be completed without modifying pipeline structure, reducing procurement cycle and cost of imported parts;

2. High Maintenance Safety: Built-in independent pressure relief drain port allows controlled pressure relief before accumulator disassembly, preventing medium spray and pipeline shock hazards caused by pressurized disassembly, enhancing maintenance safety;

3. Effortless and Durable Operation: Balance cone valve structure offsets axial oil pressure, reducing switching damping; long-term frequent operation is smooth without sticking, with minimal valve core wear and stable service life;

4. Wide Operating Condition Compatibility: 31.5MPa high-pressure nominal rating combined with multi-medium and wide temperature range compatibility, covering all conventional industrial hydraulic energy storage oil circuits;

5. Easy Installation: Standardized nominal diameter specifications with 10/20/32mm three conventional sizes, connecting to industry standard hydraulic pipelines with simple disassembly and replacement process;

6. High System Integration: Can be paired with our factory accumulators, bladders, charging valves, safety ball valves, and mounting brackets for a complete energy storage accessory package, suitable for one-stop procurement.

V. Application Scenarios

1. Industrial Machine Tool Hydraulic Systems: CNC machining, hydraulic stamping, injection molding hydraulic stations; controls accumulator oil circuit on/off and enables controlled pressure relief during shutdown maintenance;

2. Imported Complete Hydraulic Equipment: Foreign-funded factory areas and original imported hydraulic units; replaces aging imported accumulator shut-off valves for domestic upgrading and maintenance;

3. Fire Protection Pressure-Stabilizing Hydraulic Units: Fire pump room energy storage accumulator oil circuit switch control, suitable for fire-specific emulsion and flame-retardant hydraulic media;

4. Chemical Fluid Hydraulic Equipment: Chemical workshop water-glycol anti-corrosion oil circuits and emulsion transmission oil circuits; controls accumulator oil circuit on/off;

5. Vehicle and Marine Energy Storage Systems: Engineering vehicles and marine hydraulic energy storage units; suitable for high/low temperature alternating environments with stable oil circuit control;

6. Automated Hydraulic Tooling: Assembly line hydraulic clamping and energy storage tooling oil circuits; convenient switching and shut-off, suitable for routine equipment maintenance and disassembly.

VI. Ordering Notes & FAQ

(I) Ordering Instructions

1. When ordering, specify the complete model, nominal diameter, and nominal pressure to match on-site pipeline medium and diameter selection;

2. For special requirements regarding drain port size, interface threads, or valve body material, please consult our company for customization;

3. The company reserves the right to optimize product structure and processes; product updates and iterations will be made without separate notice to customers.

(II) Common FAQ

Q1: Can it directly replace the imported equivalent accumulator shut-off valve?

A: This product is developed based on overseas parameters; standard diameter models have identical interfaces and pressure ratings, allowing direct interchange installation in conventional applications.

Q2: Should the drain port be kept closed during normal use?

A: Keep the drain port closed during normal equipment operation; only open it during accumulator disassembly or pipeline pressure relief to prevent oil leakage.

Q3: Does using water-glycol medium require special seals?

A: The factory equips multi-medium seals that can directly accommodate water-glycol and emulsion media; special anti-corrosion applications can use customized seal materials.

Q4: How to select among the three nominal diameters?

A: Select based on on-site hydraulic pipe outer diameter and oil circuit flow rate: 10mm for low flow, 20mm for conventional circuits, and 32mm for high-flow high-pressure circuits.
