Rotary Valve suits automated process on/off applications.
April 20, 2009 -
With pressure-assisting action of valve seal ring, Fisher® POSI-SEAL® A81 ensures complete shutoff against maximum rated pressure drop, regardless of flow direction. Interchangeable sealing technology allows valve body to accept both soft and metal seals, while opening and closing path of eccentric valve disk minimizes contact with seal ring to reduce seal wear. Used with FieldQ® rack-and-pinion actuator, valve can be installed in either horizontal or vertical orientation.
Emerson's New Fisher® Rotary Valve Uses Special Seal Technology for Complete Shutoff and Long Life
POSI-SEAL® rotary valve ensures shutoff against maximum rated pressure drop, regardless of flow direction
MARSHALLTOWN, IOWA (April 14, 2009) - Emerson Process Management introduces the Fisher® POSI-SEAL® A81 rotary valve. Tight shutoff and the long seal life capability of the A81 make it ideal for on/off applications.
Complete shutoff is made possible by the pressure-assisting action of the valve seal ring. The opening and closing path of the eccentric valve disk minimizes contact with the seal ring, thereby reducing seal wear. Interchangeable sealing technology allows the A81 valve body to accept both soft and metal seals.
The POSI-SEAL valve is highly suited to automated on-off, quarter-turn performance and is typically used with the FieldQ® rack-and-pinion actuator. The valve is available to ship in two weeks to meet day-to-day and emergency needs. The new rotary valve can be used in most process on/off applications; it installs easily in either a horizontal or vertical orientation with no detriment to performance or cycle life.
