The API 6D Specification is an adoption of ISO 14313:1999, Petroleum and Natural Gas Industries-Pipeline Transportation Systems-Pipeline Valves. This International Standard specifies requirements and gives recommendations for the design, manufacturing, testing and documentation of ball, check, gate and plug valves for application in pipeline systems. 6D is the primary specification used for API Butterfly Valves Engineering360Resilient Seated Butterfly Valve -- STW Series from Assured Automation. Description:The STW/STL is a resilient seated 125/150, ductile iron, high performance wafer style (STW) or lug style (STL) butterfly valve available with either BUNA-N or EPDM seats and a choice of disc materials (316SS, nickel plated ductile iron, or bronze).

Butterfly Valves - Grainger Industrial SupplyButterfly valves isolate fluid flows for throttle control and have a disk-shaped closing mechanism for fluid shutoff through an actuator visible on the outside of the valve. View More Wafer-Style Butterfly Valve, PVC, 150 psi, 4 in Pipe Size. Item # 26X017; Mfr. Model # BYCS1040E1LGA Butterfly Valves - RFS HYDRAULICS MYButterfly valves are designed to regulate or isolate the flow in a system. The valve has the ability to start, stop or restrict the flow in a system pipeline and is used for repairs, cleaning or alterations of fluids when no fluid is running through the pipeline. A butterfly valve does not look much like a butterfly and it operates in quarter turn.
1. Lower the valve into the open pipe work with the disc in the 10° open position. Valves with non-spring actuators are shipped in this position. 2. Once the valve is placed in the pipework, turn the disc to the full-open position. Gradually remove the flange spreaders. 3. Center the valve body to the flanges and tighten the bolts hand-tight.

With years of experience and R&D activities, Swater has successfully developed some high end valve products such as Pipeline Ball Valves. News & Articles Swater Flow Group ISO-9001 Certified Facility The difference and selection of electric wafer butterfly As one of the most common valves in pipelines, the electric butterfly valve is used to realize the on-off of various media in the pipeline system and the control of the flow rate. It has been widely used in many fields such as petroleum, chemical industry, metallurgy, and hydropower. application. Then in the commonly used Types of Butterfly Valves (API 609) - ProjectmaterialsSep 20, 2017 · BUTTERFLY VALVE WORKING PRINCIPLE. The key component of a butterfly valve is the disc, a metal ring which is positioned at the centerline of the pipe and connected to an external actuator (manual level or actuator) via a rod.. Compared to a ball valve, the disc of a butterfly valve is always in contact with the fluid conveyed by the pipeline and creates, therefore, a pressure drop.
Nov 01, 2011 · API 6D is the primary standard for valves used in pipeline service, including gate, plug, ball and check valves. Occasionally refinery and petrochemical purchasers will reference the more stringent testing requirements of 6D although the valve may have built under API Types of Butterfly Valves (API 609) - ProjectmaterialsSep 20, 2017 · Leave a Reply Cancel reply. A butterfly valve is used to shut off or modulate the flow of a fluid (isolation and regulation). API 609 Centric butterfly valves (soft seated) are preferred to gate and ball valves for low-pressure and non-critical applications as they are cheaper, lighter and easier to install. Eccentric butterfly valves (double offset and triple offset valves) with metal seats have surged in popularity and compete with globe and ball valves
