Air-operated Valve Test Equipment - Positive/Negative Pressure Seal Testing for DN50-DN400 Breathing Valves

 

Product Introduction

The HJVTE-009 Breathing Valve Test Equipment is a specialized device used for evaluating the performance of breathing valves. It provides precise measurements of positive and negative pressure, as well as valve seat sealing integrity. This equipment is essential for the factory inspection and safety testing of breathing valves, ensuring that they meet the required standards for safe operation. The device is equipped with advanced features such as a flow meter for both exhalation and inhalation, and an AT-31 computer recorder with proprietary software for generating detailed test reports.

 

Product Features

  • Precision Testing: Measures exhalation and inhalation opening pressures, as well as leakage rates.
  • Flow Meter Integration: Equipped with a flow meter for accurate measurement of both exhalation and inhalation flows.
  • Automated Clamping System: Supports a wide range of valve sizes (DN50 to DN400) with automatic clamping.
  • Computerized Data Recording: Features an AT-31 computer recorder with proprietary software for generating comprehensive test reports.
  • User-Friendly Interface: Simple and intuitive operation for ease of use in various testing scenarios.
