Hydrostatic shell testing

Many times a client of ours will ask us to do additional testing to the valve/s before they purchase. One of the tests that is asked for is called hydrostatic shell testing and because we have our certification for API 6D such a test like this is no problem at all. Hydrostatic shell testing means that the shell, or the body of the valve will go through a pressure test. All valves MUST be hydrostatic ( WATER) shell tested to verify the valve can handle…

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,…

Pipelines Ball Valves: An inside story

When I first started working at a valve company I had to research quite a bit on what valves were and what they were used for. Yes, I was a newbie. There is so much information on the web today that I could go on and on but focusing on one of the products that the company is most known for will cut down my blog from about 10 pages to a paragraph. (Plus, who wants to read 10 pages!!?) Trunnion ball valves are the…

What are Actuators?

What are actuators? What are actuators and how do they work? There are four types of actuators that are used today.  The most commonly used in this industry are the Pneumatic and Hydraulic actuator. A hydraulic actuator consist of a cylinder or fluid motor that uses hydraulic power to facilitate mechanical operation. The mechanical motion gives an output in terms of linear, rotary or oscillatory motion. Because liquid cannot be compressed, a hydraulic actuator can exert considerable force, but is limited in acceleration and speed. A pneumatic actuator converts…
