New Keystone Brewseal seat for hygienic valves

Tyco Flow Control has announced the addition of a new high temperature seat for its popular Keystone Optiseal range of butterfly valves, popular in the food and beverage industry for over 25 years

The new Brewseal will extend the operational life of typical units in some common applications - especially in the onerous brewing conditions including hot wort - while still remaining competitive in price.

Importantly the one-piece wafer-thin disc stem of the Keystone Optiseal combines high strength with positive disc control while offering minimal disc obstruction to flow.

The disc stem can be offered with a polished finish making it ideal for hygienic duty.

The new seat is rated for 150Centigrade constant service while also offering excellent abrasion resistance for brewing, a variety of other hygienic applications and semi-aggressive chemical industries.

As with previous models the primary seat formed by the seat/shaft/hub assembly exceeds the pressure rating of the valve ensuring that the body is totally isolated from the flowing medium.

The valve body is also finished in silver Ameron PSX700, a unique high gloss engineered siloxane to suit the rigorous requirements of the hygienic market.
