Festo Monostable Pneumatic Solenoid Valve, G 1/4 Valve, Closed - VZWD Series - VZWD-L-M22C-M-G14-30-V-1P4-R1 This pneumatic solenoid valve from Festo is a simple and versatile choice for pressurised systems. It periodically shuts off the flow of air, process gas or water and is ideal for use in high-pressure applications with low flow rates. The G 1/4 thread means it's compatible with most standard valves, while a mechanical spring makes it easy to reset the valve at any point. Two-port valves like this one are used to manage pneumatic actuators such as cylinders, turbines and diaphragms. • IP (ingress protection) 65 rated, so it's sealed against dust and low-pressure water
• Stainless steel body is durable and non-corroding
• Inline mounting style means the valve mounts directly in the fluid lines for simple installation
• Built-in NC (normally closed) for safety Application Information • High-pressure cleaning equipment
• Process automation
• Vacuum technology What is a direct-acting valve? A direct-acting valve is triggered by the solenoid and doesn't need any difference in pressure between the inlet and outlet ports in order to operate. You can use it in negative pressure circuits. When should I use a 'normally closed' valve? Use a 'normally closed' solenoid valve in systems where it's safest to block flow in the event of malfunction.
