Festo Pneumatic Manual Control Valve, 3 Ports, 2,200L/min Flow Rate - MS4-EM1-1/4

Control airflow and relieve pressure in your pneumatic system with this Festo pneumatic manual control valve. Its 3/2 bistable valve function allows you to turn single-direction airflow on or off and vent excess pressure when the system shuts down. The G (also known as BSP or BSPP) thread standard makes it easy to install in your existing UK or European pneumatic system. A wide temperature range from -10°C to +60°C means you can use this valve control system in the most demanding industrial environments.

• Aluminium housing material is resistant to corrosion and suitable for use in damp conditions

• Nominal flow rate of 2,200L/min suits industrial-level pneumatic airflow systems

• Modular design means you have the option of adding a silencer to the third port to dampen the noise of the exhaust

• Standard G1/4 port makes installation simple in compatible systems

Applications

• Automated production lines

• Factory facilities

• Automotive manufacturing

• Construction projects

What pressure range can this valve handle?
