HH2I Profile Chokes NOM 4″

Our HH2I Model is a conventional needle and seat type choke which is available in both positive and adjustable configurations. It is manufactured in 3000 PSI, 5000 PSI, and 10,000 PSI pressure classes and features a maximum orifice size of 3”. The design of this choke is based on the popular Cameron® H2 and features full interchangeability of parts. The main feature of this choke is the internal acme thread in the choke body which allows for a significant reduction in weight of component parts used in the assembly. The HH2I is a great choke when a reliable large bore choke is required. The 3M/5M model is supplied with a conventional stem while the 10M model features a pressure balanced stem which provides for lower operating torques.
