Pinch Valve Types & Classifications 
Acro manufactures both solenoid and pneumatically actuated pinch valves.
Pneumatic valves are powered by compressed air
or gas, which generates a force that acts on the piston/plunger.
Solenoid valves are powered by electrical energy
passing through a solenoid to induce a magnetic field,
which then supplies force to a magnetic plunger.
