Model WPB-30 & -40
These are the improved version of standard needle & seat type chokes, where the operating torque is significantly reduced by balancing the pressure across the gate.
- Lower torque eliminates the requirement of gear box thus considerably reducing the number of turns to operate the choke.
- Elimination of gear box makes field maintenance easy. It also eliminates the possibility of over-torqueing the stem, thus prevents the possible damage to the trim components.
- The indicator is designed to show the exact bean size in the window.
- Available in high pressure with larger trims i.e. 2” and 3” orifice.
