Yulin Machinery is one of the Chinese manufacturers of API 6A gate valves. The API 6A gate valves manufactured by Yulin Machinery are divided into ball screw gate valves, API 6A expansion gate valves, API 6A hydraulic gate valves, Slab Gate Valve, API 6A Choke Valve, etc. Their functions are as follows.
Ball screw gate valves are designed for large caliber, high pressure manual valves. The valve combines the tail balance lever and the unique ball ball principle to make its operation light, low torque, easy to operate.
API 6A Expanding gate valves are an excellent choice for controlling the flow of liquid or gas in the industry. API 6A Expanding gate valves have now become widely popular over recent years. The body is made of forged or cast alloy steel, or stainless steel, rating up to 20000PSI, end connection is available in flange, screwed etc, widely used in high pressure and high temperature working medium.
We design our API 6A Hydraulic Gate Valves to be Pipeline/Wellhead valves you can trust. These API 6A gate valves meet all of the industry standards for quality and safety. We have the full line of replacement parts available for our API 6A Hydraulic Gate Valves, and we are determined to meet the needs of our customers for dependability and availability.
Flat gate valve widely used in oil, natural gas long-distance pipelines and gas fields Valves used in forging or casting body, the gate designed with diversion holes, non-diversion holes; single discand double disc structure; Seat used bi-direction seal seat which mainly based on the metal seat sealing and assisted with soft seat sealing as a second type of seal. The series of parallel type gate valve has rational design, compact structure, sulfur resistance, corrosion resistance, wear-resistant, reliable sealing, and light torque of switches, easy-to-use.
Yulin Machinery Adjustable choke & Positive choke valves are often used in the oilfield when drilling,testing,production our adjustable choke valve is designed and manufactured in accordance with API 6A and API 16C standard and improved from customer feedback. They are easy for operation and simple to maintain.
