This blog post would cover the three main types of control valves which you need to know about, they are essentially DBB, ball and manifold valves.
- Double Block And Bleed Valves
The DBB valve provides the main primary isolation when it is directly mounted onto a process pipe work.
- The assembly of floating ball valves
- Heavy duty needle valve assembly
- A forged one-piece body for a superior flow grain
How A DBB Valves Works
The single units of these kinds of valves are mostly used for applications where a complete certainty of shut-off is required for the fluid or gas. In some cases where space is limited, a valve will need to be very effective but also have a compact size which is another positive advantage of a singular unit.
The API flanges are also available and can be up to an impressive 10,000lbs for the inlet unit valves.
Standards: Gas pressure Testing to BS 6755, fire safety materials, the material certification can also be provided on request for all materials including the stainless steel, Monel 400 as well as Hastelloy.
- Manifold Valves
The manifold system is a kind of control valve which can be used for isolating and controlling the flow of media within a system. Some of the adaptable instrumentation valves include the 2 way, 3 ways as well as 5 way manifold valves. They are specially designed so as to replace the multiple unit which are assembled for reducing leak points and also save space because of their compact form.
This kind of valves is also used in different applications so as to regulate the flow of media which is between actuators and pumps.
For those that have interest in the growth as well as trend aspect, below is an article about the market of ball valves and manifolds.
- Ball Valves
Ball valves are a type of control valve that are excellent for shutoff applications.
- Ball valves are a kind of control valve which are excellent for shutoff applications
- Key Features
- The standards include the 1000, 3000 as well as 6000 psi rated ball vales
- Up to 10,000 psi rated on request
- Color coded functionality so as to make the installation and replacement easy
- It is compact and reliable
- It has a long service life if properly maintained
- Pressure VS. Temperature
The flow of air and water pressure drop chart can be seen in the catalogue which is provided for a precision valve and you can easily make reference to it. Those that have been tested for a pressure vs. temperature performance include the 0.25”, 0.375”, 0.5” as well as 1” ball valves.
The temperature rating as standard for the ball valves is -45 – 230C and up to 6000 psi safe working pressure.
The Issue Of Corrosion Resistance
The valves which are resistance to corrosion are manufactured from materials which have special properties such as alloy. The attributes of high performance alloys such as Hastelloy, Titanium as well as Inconel 625 are suitable in environment which corrosion is very rampant. The effectiveness of the valves resistance depends majorly on the kind of alloy which is chosen. Free advice is also offered by engineers about choosing the correct material for manufacturing the application which is needed.
