These are used in many oilfield applications to control the rate of flow. Usually, an adjustable choke is used as part of a manifold installed downstream of the wellhead. The choke is adjusted during the flow back of the well to control downstream pressure and flow rates. The PARVEEN adjustable choke is comprised of three main sub-assemblies. These sub-assemblies are the bonnet, tee, and nipple assemblies.

PARVEEN chokes are available in 3/4”, 1”, and 2” maximum orifice sizes with Fig. 602-1502 hammer union connection.
