It can directly pressurize and open the valve conveniently in spite of external conditions. Bright red-colored knob on manual valve provides highly visible local verification of system status being tripped.

All components are integrated on one manifold, with all channel connections among each part designed within the module. The structure is compact, reliable and no leakage even in extreme temperatures. Sub-plate and control components are constructed of corrosion-resistant anodized aluminum with stainless steel internals with IP68 protection.

The whole system adopts volume compensating design, with the hydraulic control loop totally isolated with air, avoiding deterioration or contamination of the hydraulic oil. Especially, this self-contained emergency shutdown valve can be installed at any angle necessary.

Specialized troubleshooting design provides a quick self-diagnosis system. With the help of handbook, the site engineer can get the real situation, and solve the issues by themselves or feedback to our technical support team.

Temperature compensation of high pressure actuator circuit and low pressure control circuit is accomplished with two separate accumulators. Assures system stability by minimizing relief valve operation and eliminating valve drift due to large temperature changes.
