Sizes |
2” (50mm) to 84” (2100mm) |
Pressure Ratings |
ANSI 150# through 2500#. |
Torque |
Under high pressure (14.5 Bar/210psi) the torque required to operate the valve was 160 N.M |
Seal Temperature |
During test burn period, where temperatures reached 1652°F (900°C) the high integrity metal/metal seal still ensured tight shut off |
Bearing Protector |
Enables arduous duty applications where solids may be present in the flow media. |
Live Loaded Packing |
A set of Belleville spring washers fitted to the gland follower provides automatic adjustment to packing. |
Steam Jacket |
integral steam jackets are available on the double flanged body design |
Lantern Ring |
Available for the packing box |
Ease of actuation |
Rotary action of the valve enables ease of actuation and suitability for either control or isolation |
Superior gland performance |
Rotary motion valves greatly reduced fugitive emissions from gland packing. In addition gland packing life is considerably improved |
