What does it mean to be API certified?

When a valve manufacturer is API 6D certified it means that they have a certificate that certifies their valves are tested to API standards. There are different specifications of API. For instance, API 6D is a specification for pipeline valves. “API 6D specifies requirements and gives recommendations for the design, manufacturing, testing and documentation of ball, check, and gate valves for application in pipeline systems.”  Not only are our Trunnion ball valves API 6D certified but we also carry the API Q1 specification. This allows…

Types of Ball Valves

Types of ball valves :   Different types of bores for ball valves – full port, reduce port and V-port. These three types have different constructions and purposes.   Full Port Ball Valve – A full-port, also known as a full bore, ball valve has a bore internal diameter (ID / inside diameter) approximately equal to the pipeline ID. This allows for reduced friction and pressure loss across the valve. With a full port ball valve there is NO restrictions to the flow of medium,…

Understanding Stainless Steel Ball Valves

Stainless steel ball valves are definitely one of the popular materials that many people buy. They are perfect for the food and beverage industry, agriculture as well as the pulp and paper industries. The reason behind this is because stainless steel does not corrode and when dealing with food which we consume you do not want your machines corroding. White it is true that stainless steel (SS) does not easily corrode or rust, it really depends on the oxygen level in atmosphere. For example, if…

Lubricants for Your Valves’ Gearbox

Theory: Cold weather dictates a different type of lubricant to avoid seizure and promote proper function inside the gear housing. Global Valve and Controls states, “in order to have a proper functioning valve it is necessary to use the correct grease inside the gear housing.” In a case study where non-cold rated grease is applied to a valve that is heading to Wyoming, where the weather can be frigid seven months out of the year; the likelihood of the valve seizing becomes increased and the…
