Choke Valve

Choke Valve introduction

Choke valves fall into five types: fixed choke valve, needle choke valve, plunger choke valve, cage-type choke valve and orifice choke valve.
The application of the materials, of which the main body and the components of choke valves are made, tallies completely with the API 6A and NACE MR-0175 standards. These choke valves are extensively used in off-shore and land oil drilling operations and also in oil production.

Features:
● Fitted with a valve-opening indicator
● Designed with the relief valve
● Designed with the plane thrust bearing structure
● Designed with the metal-to-metal sealing structure
● Fitted with the valve stem sealed by using some special material made lip-shaped packing
● Made of high wear-resisting & corrosion-resisting materials, both the valve core and bean are durable
● Designed and manufactured strictly in accordance with API Spec 6A, ANSI and NACE MR-0175 standards.
