Oil And Gas Valve

High performance, two-way sealed flat gate valve has good performance under high pressure and can be applied to oilfield wellhead, Christmas tree and manifold system from 2000 to 15000 psi. SGA / B series rigid flat gate can be replaced by expansion gate. Materials suitable for H2S medium shall be selected according to the new NACE mr-01-75 specification

Choke valves fall into five types:the fixed choke value ,the needle choke value ,the pluger choke value ,the cage-type choke value and the orifice choke value. The application of the materials,of which the main body and the components of choke values are made,tallies completely with the API6A and NACE MR-0175 standards. These choke values are extensively used in off-shore and land oil drilling operations and also in oil production.

Mud gate valve is specially designed for strict oil well conditions. It can reliably operate under corrosive conditions, The performance makes GAIRUI mud gate valve the choice of oil and gas drilling fields

This product is designed and manufactured fully in accordance with API Spec 6A wellhead and Christmas tree equipment standards,and can thus be used interchangeably with the products manufactured at home and aboard,which tally with API Spec 6A specifications ,or used to form a complete system.
This is a type of check values which rely on the pressure of working medium to get meal-to-meal sealing between the core and body(seat). The higher the medium pressure,the better the sealing performance. It is always able to withstand the pipeline pressure within the value cavity.
The body of the value is forged with alloy steel,which has solid mechanical properties and is able to withstand high pressure in safty and reliability.
The bonnet and the body of the value are connected with blinding bolts. Sealing washers are used to seal up the bonnet and the interior wall, which reduces the space in between to a minimum (designed as 0),thereby considerably minimizes the erosion of the bolts and the bolt holes,caused by erosive  media,and also decreases the load taken by the bolts.
The sealing surfaces of the both the value core and body are built-up welded with carbide alloy and therefore have excellect wear-resisting and corrosion-resisting performances. With the value core being made of sulphur-resisting material and the other parts being manufactured by use of hardness-limited technology,this type of values can be used into the environment whereH2S s contained.

Plug values are indispensiblefor connecting the high-pressure manifold during cementing and fracturing operations  in oil fields. They are also used for similar high-pressure fluid control operations. Up to now,this product is ideal for use in cementing and fracturing manifoldsbecause of its good features such as compact structure,small torque ,easy maintenance,quick opening action and labor-saving,ect.
