Valve-Prop Comprehensive Test Bench
GB25974-2010 Compliance – Meets strict coal mine hydraulic valve testing standards.
Multi-Valve Testing – Covers check valves, safety valves, directional valves, and shut-off valves.
High-Pressure Capacity – Supports up to 80 MPa for rigorous testing.
Dual Fluid Compatibility – Works with hydraulic oil & emulsion for flexible applications.
Precision Monitoring – Class 1.6 pressure gauges ensure accurate test data.
Product Introduction
This Valve-Prop Comprehensive Test Bench is designed in accordance with the GB25974-2010 "Hydraulic Supports for Coal Mines" standard, enabling rigorous testing of hydraulic support valves, including check valves, safety valves, shut-off valves, and directional valves (plate valves). It also supports testing for single props, hydraulic cylinders, and jacks.
Key Features
Standard-compliant testing system – Ensures test conditions meet GB25974-2010 requirements.
Manual operation with pressure gauge readings – Test procedures strictly follow factory testing standards, with real-time data displayed on precision pressure gauges.
Testing Capabilities
Check Valves – Tests include opening pressure, closing pressure, control pressure, and high/low-pressure sealing.
Safety Valves – Evaluates pressure adjustment range, opening/closing pressure, sealing performance, and generates low-flow pressure-relief characteristic curves.
Directional Valves – Tests directional function (low flow), high/low-pressure sealing.
Shut-off Valves – Conducts high/low-pressure sealing tests.
