Shut-off valves are another type of valve that stops the flow of air in a pneumatic control system. The valve quickly stops the flow of the medium. The name shut off valve is a general term for all types of valves that either continuously block air flow or block flow when requested such as a manual shut off valve. Shut off valves can either require a mechanical or electrical signal to stop flow, or in the case a a logic valve requires a set pre-set conditions to allow flow.

What are Shut Off Valves?

Shut off valves come in many types, including non-return and exhaust valves, butterfly and ball valves, simple on-off valves and logic valves. Shut-off valves can also be operated by a solenoid which closes the valve with a spring action, or can be a pneumatically-controlled, one-way valve. This type of valve stops the movement of the cylinder and de-energises it, while variant versions also incorporate cylinder adjustment as well as stopping.

Ball valves are a sturdy and versatile solution for neutral or moderately aggressive gases or liquids in industrial applications, water treatment systems or building systems. More robust versions tackle very aggressive or corrosive substances such as chemicals or petrochemicals and biopharmaceuticals. They are also suitable for clean rooms used in applications like life sciences and the semiconductor industry, the food and beverage industry and mining.

Logic valves are multi-functional, electronically controlled valves that can sequence and control the flow of air in pneumatic systems, and include twin pressure valves for limiting either the main flow or a pilot operation. These use single or twin actuator ports and can control a greater flow rate, while shuttle logic valves can be used for mobile applications.
