Pentair's enclosures for hazardous locations offer reliable protection for the pilot valves of your filter cleaning system in high-risk environments. The Goyen and Mecair enclosures are dust and gas explosion proof and will operate safely even in the most extreme conditions.
Pilot valves control a limited-flow control feed to a piloted valve which typically controls a high pressure or high flow feed. Often used in critical applications such as safety controls, pilot valves need protection against dirt, moist, tools and other outside influences that could have a negative impact on availability and reliability.
Pentair’s enclosures for hazardous locations have pilot bodies, covers and enclosures manufactured from pressure die cast aluminium. They are designed to operate with compressed air manifold pressures ranging from 30 kPa (5psi]) to 860 kPa (125psi).
Pentair’s pilot valves may generally be installed in any orientation, although it is preferable to mount the solenoid above the valve to minimize the ingress of dirt and foreign matter into the ferrule tube. They are able to operate within a wide temperature range, depending on the certification (ATEX/IECEx: −20°C to +40°C (-4°F to +104°F), CSA/UL: -25°C to +40°C (-13°F to +104°F). For reliable operation, ensure the supply voltage is no more than 15 percent above or below the rated solenoid voltage.
