Positive Choke provides a fixed flow condition with a large selection of available bean sizes and types. All standard positive chokes under 15000psi wp are furnished with a blanking plug that has a 1/2" NPT port for attaching a needle valve and/or pressure gauge. Positive chokes 15000psi wp and over are supplied with a 9/16" autoclave port.

Features

Positive choke bodies are interchangeable with adjustable needle chokes.

A bleed valve allows the operator to safely vent the body cavity pressure prior to the removal of the bonnet assembly.

Body pressure is automatically vented when the operator unscrews the bonnet nut one turn.

ACME threads can be cleaned and inspected easily on both the bonnet assembly and body.

CAN type choke prevents bonnet seal extrusion by means of body-to-bonnet contact behind the O-ring seal.

The bean/seat has been recessed in the body below the inlet flow path for longer life.
