BALL VALVE, CS, TM - Flow Fusion
BALL VALVE, CS, TM 。 Design Rang f Materials Cast steel ball valve are designed and manufactured to provide maximum service life and dependability. All gate valves are仙H ported and meet the design requirements ofAmerican petroleum Institute StandardAPI 600 &API 6D, B「itish Standard BS 5351 and generally conform to American Society of Mechanical Engineers Standard ASME B 16.34. Valves are available in a complete range of body/bonnet materials and trims. S饱ndar咀body/bonnet materials include nine grades of carbon, low alloy and stainless steels. For special applications they can be supplied in other grades of alloy and stainless steel. There's a full range of trim materials to match any se阿ice. Optional packing and gasket materials are available for a full range 。，f service conditions. 。 。 。 Available M dificati ns F r Cast Steel Valves * Trim changes * End connection Modifications * Packing and Gasket Changes * Operator Mounting * Handwheel Extensions Operating * Pressure Equalizing *AS 口「 FD * Customer specified Coatings * Weld End Bore Changes Oxygen & Chlorine Cleaning & Packagi『1g .§) Packing BORE Extended lever for easy operation.

Graphite packing use situatior for high-temperatu『＠ 。 AS Anti Static.A metallic contact is always granted between ball and stem/ body to discharge eventual statics build-op during service. DDB Double Block & Bleed, The body cavity is isolated when the ball is in either fully closed of fully opened positi口n The medium entrapped in it can easily be bled to avoid over pressure ID FD Fire Durable. Designed toAPI 607 or BS 6755 to grant their operation suitability in case of fire. Secondary metal-to-metal seal acts as backup if primary seal is destroyed by fire. Valves ordered for compliance withAPI 607 will be provided with graphite packing and gaskets. 7 l A『

through 24) V150, V200 and V300 Vee-Ball control valves. The Vee-Ball valve combines globe valve ruggedness with the efficiency of a rotary valve. The Vee-Ball valve is a segmented ball valve which features a contoured segmented V-Notch ball. A shearing action between the V-notch ball and the ball seal (figure 1) promotes smooth, nonclogging .
When choosing the right three-way ball valve, it is important to both understand the key three-way valve design options and plan how the valves will be used. First, some basics. What is a three-way ball valve? Three-, four- and five-way ball valves are called multi-port valves. The three-way ball valve is the most common multi-port ball valve.
Ball Screw Selection White Paper Ball Screw Basics A ball screw assembly consists of a ball screw and a ball nut with recirculating ball bearings. (Figure 1) The interface between the screw and the nut is made by ball bearings that roll in matching forms in the ball screw and ball nut. The load on the ball screw
