Forged EE PR2 H2 Type Manual Choke Valve For Wellhead

API 6A H2 Type Manual Choke Valve for Wellhead

Product Introduction

The choke valve, a main Description of Christmas tree, is design to control production rate of the oil well, with working pressure up to 10000psi. Choke valves can be classified as follows: Adjustable choke valves and positive choke valves.

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.

The hydraulic choke valve is employed on manifolds and other assemblies and designed for flow control. In order to control flow rate, the hydraulic choke valve uses the valve core which can be lifed and lowered to adjust the effective area available.

How to maintain the choke valve?

• When the product is stored, the end flanges shouldbe coated by oil against rust and dirt pollution.
• Every seal element is replaced according to itsexamination.
• As leak appears at the middle one of the valvebores, ring gasket should be replacedThe valve should be placed in the dry and airy room,and the inlet and outlet are sealed properly.
• There is a bit leak at a couple of seals of valve, andthe sealing-face may have scratch or wear. Renovationwill be done under face-off and ground finish.
• The valve-core and the valve-seat must be exam-ined every in a well time. The attrition rate will decidewhether they are used by upset or are replaced.

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.
