Needle valve

with handwheeladjustmentchoke

Jereh Choke Valve consists of needle type adjustable choke valve (JFK), positive choke valve (JFG), barrel type choke valve (JFT), cage type choke valve (JFL) and orifice type choke valve (JFB), mainly used in onshore and offshore oil drilling and exploitation. The design and quality control conform to international standards. Bodies are made of premium low alloy steel, processed with advanced technology in conformance with API 6A 20th edition and NACE MR-0175. Features Needle Type Choke Valve Mainly used on wellhead Christmas trees Valve plug and choke bean adopt high abrasion resistance hard alloy to endure long hours erosion and corrosion. Open indicator and safe lock relief device Available with pressure relief valve. JFK needle type choke valve and JFG positive choke valve are interchangeable in body of the same size. Barrel Type Choke Valve Used on choke and killing manifold to control casing pressure during drilling operation. Easy flow adjustment, allowing stable flow. Stem seal is made of special materials, delivering good chemical stability and corrosion resistance. Valve plug and choke bean adopt high abrasion resistance hard alloy to endure long hours erosion and corrosion. Barrel-shape gate, annular gap between gate and seat with entry and outlet connecting all the time, mainly used on choke manifold or other high pressure lines
