Product Description

Product Description
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.
