API 7 1/16" Wellhead Adjustable Choke Valve For Oilfield

API 7 1/16" Wellhead Adjustable Choke Valve for Oilfield

Product Introduction

Choke valve is a main component of Christmas tree, is design to control production rate of the oil well, with working pressure up to 15000psi. Choke valves can be classified as follows: adjustable choke valves and positive choke valves. By rotating hand wheel to move the stem, the adjustable choke valve is designed to adjust the effective area available for the flow to accomplish control of production rate. The positive choke valve is design to accomplish control of production rate by changing flow beans.choke valves are supplied in two types: Positive and Adjustable. It's designed as per API 6A, API 16C, NACE MR0175, the structure Type: needle, barrel, cage, orifice and wedge.

Valve body is machined of alloy steel forging with astronger machinery properties and reliable performance.
Bonnet is connected with valve body with bolt, theseals include the sealing ring in the bonnet and the sealin the valve body;
The sealing face between valve core and valve bodyis welded with hard alloy with good abrasion resistanceand anti-scour; the valve core is made of sulfide-resistance steel and the others adopt the process of hard-ness limit so the valve is able to be used in H2S condition.

Operation instruction

According to medium flow direction and by the flowdirection indicating plate of the valve, the valve isinstalled. As positive flowing, The medium lifts the valvecore and pass easily; If no positive medium pressure,valve core will self-shut off valve gate under self-weightand spring's tensile force, the back medium flowing stop.

Main Benefits of Our Oilfield Choke Valve

• The choke valve improves well production time and enhances control at wellhead.
• It is easy to mainten and repair the choke valve, which reduces oilfield operation costs.
• The choke valves improve ability to accommodate change in well operating conditions.
