What is a unibody ball valve?
What is a unibody ball valve?
The Keckley Style BVF1 Unibody flanged end ball valves are constructed from rugged investment castings that are machined to exacting specifications. Unibody construction provides high structural strength and minimizes external leak paths.
What is the difference between trunnion and floating ball valve?
The ball in a trunnion ball valve is supported by the stem and trunnion, reducing the operating torque, while the seats are spring loaded. In a floating ball valve, the ball floats and the seats are fixed while the ball is only supported by the stem.
How does a floating ball valve work?
Floating ball valves are operated by a shaft, or stem, attached to the top of the ball that turns it 90 degrees (a quarter turn). As the ball rotates, the port is covered or uncovered by the wall of the valve body, either releasing or halting the flow of media.
What is a split body valve?
As an alternative to one-piece ball valve body designs, a new split-body valve series with a two-piece bolted-body design meets ANSI take-out dimensions for either a long full port or short reduced port pattern. Engineers typically discard larger, one-piece body valves when seat failures occur.
Why reduced bore valves are used?
The reducing ball valve is suitable for conveying gas or medium with physical properties similar to water, because its weight is about 30% lighter than the full diameter ball valve, and its flow resistance is only about 1 / 7 of the same diameter globe valve. It is beneficial to reduce pipeline load and cost.
How do you tell if a ball valve is open or closed?
Ball valves are perhaps the easiest valve to see if they are open or closed. If the handle on top is parallel to the valve, it’s open. Likewise, if the handle is perpendicular to the top, the valve is closed.
Is a ball valve the same as a globe valve?
Ball Valves vs Globe Valves The main difference between these two types is the way they close. A globe valve uses a plug (stem) that closes against the flow, and a ball valve has a gate (ball) that closes across the flow. They are designed with a stem that moves up and down inside the valve to control flow.

Why choose KTM ball valves?
KTM Ball Valves Innovative ball valves for demanding applications An unending search for excellence has seen KTM become the premium brand for industrial ball valves. 2 |KTM |3 INNOVATION MILESTONES Since pioneering the development of ball valves in Japan, KTM has built the experience and expertise required to meet virtually any type of user demand.
Why choose an OM2 ball valve from kilktm?
KTM’s record in polysilicon applications – particularly its OM2 ball valves – and a proven reputation for quality made the solutions the perfect choice. So did performance, such as the ability to manage temperatures from ambient to 150°C (302°F) and rated up to a maximum pressure of Class 300.
Why choose KTM 3-way ball valves for HF vapour Transflow systems?
A major US chemical company has replaced existing solutions with KTM 3-way ball valves to optimize its HF vapour transflow systems. In addition to providing an immediate boost in terms of service life, the side-entry design also offers a much lower pressure drop than more common, bottom-entry designs.
