Maxitrol Model BV250 Manual Ball Valves

Manual Ball Valves
Model BV250

Ball valves from Maxitrol for gas, water, oil, steam and other applications have a strong body of forged brass, female NPT inlet and outlet, hard chrome plated ball, and anticorrosion Dacromet treated handle. BV602 models contain seats of Buna N, and are of one-piece construction. BV250 models contain seats of PTFE (Teflon®), and are of two-piece construction.Each of the two standard models is equipped with a different lever style handle (see reverse).

A Self Locking Nut improves reliability between the stem and lever by providing additional stability against vibrations. In addition to the seal created by the ORing, a PTFE anti-thrust washer seals against the shoulder of the valve.

The valves also feature innovative designs of the ball and seat. The hollow ball design is based on R&D lab work and years of field experience. Manufacture of the hollow ball requires a technical level not found in most substitutes. Heavier is not necessarily better, in fact the lighter ball decreases wear associated with on-off turning action. Typically the greatest friction loss takes place at the point of highest gravitational force. The lighter hollow ball increases the life of the valve seats from 10% to 20% more than with a solid ball. The valves are manufactured with a unique new seat shape to reduce friction during opening and closing. Compared with other seat shapes the maneuver torque is reduced 20% to 40%. S-model valves have side pressure taps (602S-44 shown).
