Parker Fluid Control Division offers the High Flow direct mount NAMUR solenoid valve. The product line provides cost-effective solutions for general-purpose valve actuator applications, including water and sewage, pulp and paper, food and beverage, pharmaceutical, powder-dosing machines, powder transportation, process industry, and twin-tower air dryers.
Compact in its design, the High Flow valve features a NAMUR mounting pattern and high-flow rates from 1.2 to 3.0 Cv. A spring return allows fail-safe operation in the event of a power loss, and a screened exhaust nut protects valve function during outdoor use. Additionally, the O-ring seal design increases sealing force at higher pressures and offers less breakaway resistance at lower pressures. Enjoying a long life expectancy of up to 5 million cycles, the High Flow valve has the potential to reduce maintenance needs.
The High Flow NAMUR valve offers a conversion plate for 3/2, 5/2 operation. The product is built with an anodized aluminum body and a stainless steel spool, as well as internal parts made of brass. It is designed for direct mounting in any position on a NAMUR interface. As well, the High-Flow NAMUR Valve operates from a pressure range of 30 – 150 psi.
These rugged valves are offered with class F DIN and Class H hazardous location coils. The valve operates at fluid temperature ranging from 32º – 122º F. Hazardous coil enclosures meet FM and CSA agency approvals for Class 1: Groups A – D and Class II: Groups E - G.
