Looking for reliable suppliers of cast steel valves in Dubai, UAE. Specifically, I'm interested in cast steel gate, globe, and check valves. Come across Al Hakim, which distributes a wide variety of these valves, including cast steel angle valves and cryogenic valves.
Has anyone had experience with Al Hakim's products and services?
Yes, there are.
A Plug Valve is a Globe Valve. Very generally speaking there are two major catagories of Industrial Process Control Valves, Sliding Stem and Rotary. Globe Bodies valves fall into the category of Sliding Stem Valves. Butterfly and Ball valves fall into the category of Rotary valves. However there are what is referred as Rotary Plug Valves, whereby a partial sphere has a shaft eccentrically mounted, that rotates into and out of a metal or composition seat acting as a plug. Most plug valves are sliding stem.
Y pattern globe valves allow probably less pressure drop as compared against the T pattern globe valves. I do not have experimentally proven results for this. However the flow pattern in Y Globe valve is more "linear" while that T pattern is more "zigzag". Secondly, height of the valve from its flow bores' center line till top of the hand wheel is less in Y Globe Valves, as compared against the T Globe Valves. This gives compactness to Y Globe Valves - which is beneficial in pipings where space is a constraint. [by Ganesh Devale, Pune - India]
To throttle the medium being used as a globe is NOT a positive shut off A globe valve is a type of valve used for regulating flow in a pipeline, consisting of a movable disk-type element and a stationary ring seat in a generally spherical body. For example, globe valves or valves with a similar mechanism may be used as sampling valves, which are normally shut except when liquid samples are being taken. Since the baffle restricts flow, they're not recommended where full, unobstructed flow is required.
globe valve. With a spherical valve is closed. Valves can be closed with a round handle.
Simple globe valves are not positive shut of and are used strictly for throttling thus they have a very high friction loss=Gate valves are either fully open of fully closed NORMALLY FULL PORT OPENING=
The different types of kitchen sink valves available in the market include ball valves, gate valves, globe valves, and cartridge valves. Each type has its own unique design and function for controlling water flow in a kitchen sink.

The different types of gas shut off valves available in the market include ball valves, gate valves, globe valves, and butterfly valves. Each type has its own unique design and function for controlling the flow of gas in a system.
The different types of shut off valves used in plumbing systems include ball valves, gate valves, globe valves, and butterfly valves. Each type has its own specific design and function for controlling the flow of water in pipes.
they are best with pressure and they close all the way.
Not normally unless one wants to throttle the volume
