Start and stop flow through a line

Air-Actuated On-Off Valves

Air-Actuated On-Off Valves

Operate on compressed air to start and stop flow faster than motor-driven valves

Sampling Valves

Sampling Valves

Drain a small amount of liquid or gas for inspection without disrupting flow

Motor-Actuated On-Off Valves

Motor-Actuated On-Off Valves

An electric motor handles higher flow rates and pressures than solenoid valves
