A special feature of the “Pressure-Trol” system allows the operator to regulate testing pressure and bleed off water with only two (2) centrally located controls without having to “clutch” the engine. Its safe, simple operation keeps the operator in full control of the test process. The Pressure-Trol valve is typically installed next to the control panel and often next to a chart recorder on a typical GD Energy Products hydrostatic testing unit.
