ASCO Numatics has introduced its 8361 Series of stainless steel pilot valves. The series’ unique design eliminates the dormancy or “sticking” problems that can occur in control valves installed in the pneumatic logic panels that control monitoring safety systems in offshore oil and gas production facilities.
The 8361 Series (1/4-inch NPT, 3-way, 316L stainless steel) valves are offered in manually operated, air-piloted, and solenoid-piloted versions. They can be configured as breathing and non-breathing. The non-breathing version isolates internal components from the atmosphere and is internally vented, preventing contaminants such as salt and dust to enter the valve and corrode internal components.
The valve’s balanced design maintains the same flow characteristics when the valve is used in a normally open or normally closed configuration. This provides symmetrical flow that enables more flexible setup of the control panel’s pneumatic logic.
In addition, the valve’s pilot-selector design allows the same unit to be used as an internally or externally piloted solenoid valve. The 8361 Series’ solenoid version comes with ASCO’s renowned RedHat solenoid.
