Festo Introduces the VZWP - An up to 40 Bar Servo Controlled Solenoid Valve for Water, Air, and Neutral Media Process Applications

The Festo solenoid valve VZWP features a piston seal instead of a diaphragm seal and a maximum operating pressure of 40 bar, an ideal universal process valve for water, air, and neutral media. Bottling (secondary circuit), irrigation, well engineering, sanitary engineering, water treatment, and mixing plants, pipeline construction, and pneumatic automation systems are ideal choices for the process valve.

(March 4, 2013) - The new Festo solenoid valve VZWP, which features a piston seal instead of a diaphragm seal and a maximum operation pressure of 40 bar, is an ideal universal process valve for water, air, and neutral media.

The use of a sealing piston instead of a diaphragm means that even high pressures can be controlled with a large nominal diameter. The valve closes automatically if power is lost.
The valve can be operated wherever there is a pressure difference between the valve input and output. This includes applications where the medium is expelled into the open air or flows into an unpressurized container downstream of the valves. The VZWP is used for gaseous and liquid material flows up to a viscosity of maximum 22 mm²/s in factory and process automation.

The VZWP are 2/2-way valves, normally closed and are piloted piston poppet valves. Units are made of brass valves and customers have a choice of nitrile rubber and fluoro elastomer seals. The valves come with either NPT or G threads. Units should preferably be mounted with the coil on top. Sizes range from 1/2 to 1 inch. Operating pressure is from .5-40 bar. Process valve nominal pressure is PN 40. Differential pressure is .5 Bar.

Applications for the VZWP include: Bottling plants (secondary circuit), irrigation plants, well engineering, sanitary engineering, water treatment, mixing plants, pipeline construction, and pneumatic automation systems.

"To our process valve offerings, including ball, butterfly, and gate valves, Festo has now added gas and liquid valve solutions," said Craig Correia, process industry segment manager, Festo. "These process valves provide OEMs and end users with a new one-stop-shop for both process and discrete automation solutions from Festo, one of the most respected automation suppliers in the world."

Universal Robots - Collaborative Robot Solutions

Universal Robots is a result of many years of intensive research in robotics. The product portfolio includes the UR5 and UR10 models that handle payloads of up to 11.3 lbs. and 22.6 lbs. respectively. The six-axis robot arms weigh as little as 40 lbs. with reach capabilities of up to 51 inches. Repeatability of +/- .004" allows quick precision handling of even microscopically small parts. After initial risk assessment, the collaborative Universal Robots can operate alongside human operators without cumbersome and expensive safety guarding. This makes it simple and easy to move the light-weight robot around the production, addressing the needs of agile manufacturing even within small- and medium sized companies regarding automation as costly and complex. If the robots come into contact with an employee, the built-in force control limits the forces at contact, adhering to the current safety requirements on force and torque limitations. Intuitively programmed by non-technical users, the robot arms go from box to operation in less than an hour, and typically pay for themselves within 195 days. Since the first UR robot entered the market in 2009, the company has seen substantial growth with the robotic arms now being sold in more than 50 countries worldwide.
