The Johnson Corporation Solenoid Valves Johnson solenoid valves are built to handle rugged service applications. Johnson heavy-duty solenoid valves provide a dependable way to provide automatic control of liquid or gas flow. These solenoid valves can handle practically all types of fluids-hot or cold water, steam, oil, gas, compressed air, and heavy viscous fluids, etc. The solenoid coil is placed alongside the valve rather than directly above it. All valve parts are made for a long service life with minimum maintenance.
Valves are standard cast-iron bodies and caps, bolted together.
Removal of cap screws allow easy access to valve operating mechanism.
