Featured Safety Valve Test Bench Models

  • Computer Control Safety Valve Test Bench

    Computer and Manual Valve Test Bench

    The Computer and Manual Valve Test Bench is designed for workshops and service centers that require maximum flexibility. This bench supports both fully manual operation and computer-assisted control, allowing operators to choose the most appropriate mode for each task. In manual mode, the operator has direct control over all pressure adjustments, making it ideal for experienced technicians performing routine calibrations.

    In computer mode, the system automatically controls the pressure ramp, records all test data, and generates a comprehensive test report. It is suitable for testing a wide range of spring-loaded and pilot-operated safety valves across hydraulic and pneumatic pressure ranges.

  • Manual Control Safety Valve Test Bench

    Manual Control Safety Valve Test Bench

    For organizations that require a dependable and cost-effective solution for routine safety valve calibration, our Manual Control Safety Valve Test Bench is the ideal choice. This bench provides all the essential functions for testing set pressure, setback pressure, and tightness of spring-loaded safety valves.

    The clear, intuitive panel layout allows operators to quickly set up and perform tests with minimal training. Despite its simplicity, the bench is built with the same high-quality components and precision instrumentation as our more advanced models, ensuring accurate and reliable results every time.

  • Portable Safety Valve Test Bench

    Portable Safety Valve Test Bench (Online)

    The Highlight Portable Safety Valve Test Bench is a compact, suitcase-style system that enables maintenance teams and inspection agencies to test safety valves in-situ, without removing them from the process line. The system applies a precisely controlled supplementary force to the valve stem, allowing the set pressure to be accurately determined without raising the actual process pressure to the set point.

    This eliminates costly plant shutdowns and the time-consuming process of valve removal and reinstallation. The rugged, waterproof carry case makes it ideal for field use in power plants, chemical facilities, and oil and gas installations. It is compatible with a wide range of spring-loaded safety valve brands and sizes.

  • Computer Control Safety Valve Test Bench

    Computer Control Safety Valve Test Bench

    The Computer Control Safety Valve Test Bench represents the highest level of automation and precision in our product range. Controlled by an advanced PLC and intuitive software interface, this bench automates the entire test sequence from pressurization to data recording and report generation.

    The system supports multiple test modes, including set pressure calibration, sealing test, and lift pressure verification, all with high-accuracy sensor feedback. It is designed for high-volume testing environments such as safety valve manufacturers, large-scale maintenance centers, and third-party inspection bodies that require consistent, auditable, and fully documented test results.

  • MHV-VD100/64-S Vertical Top-Pressure Valve Test Bench with Tilting & Submerged Testing

    MHV-VD100 — Compact Vertical Bench for Small-Bore Valves

    The MHV-VD100 vertical top-press valve test bench is engineered for efficient and accurate testing of small-bore flanged valves from DN15 to DN100. The vertical orientation and top-press cylinder design allow for quick valve loading and unloading, making it ideal for high-throughput production environments.

    A key feature of this model is its flip-and-submerge function: the entire test fixture can be rotated 90 degrees and submerged in water, enabling straightforward and reliable low-pressure gas tightness testing through bubble detection. The bench performs shell strength tests at 1.5 times nominal pressure, high-pressure seal tests at 1.1 times nominal pressure, and low-pressure gas tightness tests at 4-7 bar, covering all standard test requirements for small-bore valves.

  • MHV-HD300/37.5-S Horizontal Top-Pressure Valve Test Bench

    MHV-HD300 — Versatile Horizontal Bench for Medium-Bore Valves

    The MHV-HD300 horizontal top-press valve test bench is our most widely used model, designed to handle flanged gate valves, ball valves, globe valves, and check valves from DN15 to DN300. The horizontal layout is ergonomic and allows for easy valve positioning and clamping. The movable end plate can be adjusted along the length of the bench to accommodate valves with different face-to-face dimensions, eliminating the need for multiple sets of fixtures.

    Driven by our reliable air-driven high-pressure water pump, the system provides a smooth and precisely controllable pressure ramp up to 37.5 MPa. This model is the standard choice for valve manufacturing plants, oil and gas maintenance workshops, and third-party inspection bodies requiring a dependable, all-purpose valve testing solution.

  • MHV-HB300/37.5-S Horizontal Clamp-Type Valve Test Bench

    Air Tightness Test Bench

    The MHV-HB300 horizontal claw-clamp valve test bench represents the highest level of precision in our gate and ball valve testing range. Unlike top-press designs that apply axial force to the valve ends, the MHV-HB300’s hydraulic claw clamps grip directly onto the back face of the valve flanges. This means that no external compressive force is applied to the valve body during testing — a critical advantage for obtaining sealing test results that accurately reflect the valve’s true in-service performance.

    The radial and axial position of each claw is independently controlled by hydraulic cylinders, allowing the bench to automatically adapt to a wide range of flange diameters (DN80 to DN300) and thicknesses without manual adjustment. A safety interlock prevents the clamps from releasing while the valve cavity is under pressure, ensuring operator safety at all times.

  • MDV-600/15-2S Horizontal Clamp-Type Butterfly Valve Test Bench

    MDV-600 — Dual-Station Butterfly Valve Test Bench (DN50-600)

    The MDV-600 hydraulic butterfly valve test bench is purpose-built for the unique testing requirements of butterfly valves, which have a short face-to-face length that makes them incompatible with standard valve test benches. This bench accommodates both flanged and wafer-type butterfly valves from DN50 to DN600 using a hydraulic claw-clamping mechanism that grips the valve body directly without requiring flanges.

    The dual-station design features a smaller left station (DN50-250) and a larger right station (DN250-600), allowing operators to test two different valve size ranges on the same bench without reconfiguration. The right station can be rotated 90 degrees for convenient gas tightness testing. All tests comply with GB/T13927 and API 598 standards.
