Model 930A Knife Gate Valve

Model 930 is a uni-directional knife gate valve targeted towards general purpose requirements. This series retains the same high quality standards used in the more expensive models such as 940 and 950 but utilizes a more economical design that is sufficient for general purpose services.
In particular ratings are lower than the 940/950 series in larger sizes, in line with the requirements of most common applications. Valve face to face complies with MSS SP-81 standard. Metal seated valves are offered with leakage figures that are equal or better than ANSI Class IV and soft seated version provide bubble tight shut-off.
Model 930 features cast jams and guides (above 200mm) and has a two lug body design similar to the Model 950. This range also provides easy and on-site inter-changeability between manual and pneumatic actuation.
