Use this closed monostable pneumatic control valve from Festo to block the flow of fluids, gases and air in your industrial system. The unit has an electrical actuator and spring mechanism that keep it in a normally closed state, which will open to relieve pressure when overpressure occurs. A soft sealing principle means it's safe to use in pipeline systems with substances like abrasive liquids and high viscosity fluids. Install this valve to turn applications on and off and shut down systems quickly when emergencies occur.

• Die-cast aluminium housing is robust and durable for safe use in heavy-duty applications
• Nitrile-butadiene rubber (NBR) seals withstand abrasions and compressive pressures to form tight seals and protect valve integrity
• Non-reversible flow direction ensures fluid or gas doesn't flow back in the wrong direction and damage the system

• Pressurised gas bottles and applications
• Pharmaceutical and medical oxygen and gas administration equipment

When choosing a pneumatic control valve, you need to consider your flow medium, input and output pressures, and the method of valve actuation. You should also check the flow capacity needed by the system, which will determine the size of the valve.
