Valves are used to isolate, allow or control fluid flow according to their type. Gate and ball valves are used to isolate flow and when opened are mainly opened fully.
Types of industrial Valves we supply:
Gate valves have a threaded stem between the handwheel or actuator and the gate inside the valve body. Resilient seated gate valves are used in the water and wastewater industries.
Ball valves turn through 90 degrees and can be manually lever-actuated or actuated by pneumatic or electric actuators. Ball valves can have floating seats that the ball closes onto or may be manufactured with trunnion mounting. The trunnions absorb side load pressures on the valve ball. Pneumatic actuators require a source of dry filtered compressed air while electric actuators have varying degrees of complexity depending on the application. Electric actuators generally close and open slower than pneumatic ones.Sometimes substantial volumes of air are entrained in liquids so air release valves have been designed to release the air from the liquid. Check or non-return valves permit fluid flow in one direction only. These can be swing check, spring check, ball check, tilting disc, and rubber duckbill.

A Buyers Guide To Choosing The Most Suitable Valve
What will you be using the valve for? This is the first step in determining which valve is the most suitable for your project. Valves can regulate fluid and stop it, so knowing how you intend to use the instrument will help you select the most appropriate product. Secondly, you should consider the type of media that will be circulated through the valve. This could be gas or liquid, corrosive or neutral. There are many different types of valves, so it’s important to make sure that your intended media is compatible with the instrument you purchase. Now you’ve narrowed down your search, here are some further considerations to assist you in finding the most necessary valve:
- What type of valve are you after? The main types are:
- Consider the expected flow and pressure and match the valve accordingly
- Measure the specifications of the item in which you’ll be applying the valve
- Is the valve’s operation system manual or automatic?
- The valves ongoing maintenance requirements
- Consider the assembly and installation of your valve. Does it need to be bolted or screwed in? Perhaps it needs to be welded.
Common Mistakes People Make When Fitting Their New Valves
Incorrect valve installation can cause leaks and result in further damages to equipment, so it’s vital application is performed correctly. To help with your valve installations, we’ve pulled together a list of the most common errors people make when fitting their valves and provided you with some advice to ensure you fit them correctly.
- ERROR: Installing valves in the wrong plane. Unless otherwise indicated by the instruction manual, valves should be installed horizontally or vertically for the highest performance dependent on their design and application.
- ERROR: Incorrect valves and valve sizes. Research is key as not just any old valve will do. It is imperative you match the valve/valve size with the equipment you wish to attach it to. If the equipment and valve are not compatible, you’re in for a world of trouble. See above for assistance in finding the correct valve for your project.
- ERROR: Purchasing from low-quality brands. Often not as much research or care goes into the production of valves from cheaper manufacturers. Premium valve manufacturers such as VAHN-TECH and John Valves work with leading engineers and industry experts to develop practical, strong, and long-lasting products. It’s recommended you purchase valves from leading manufacturers to avoid premature breakdown and further damages.
- ERROR: Overtightening. While you want to make sure that your valves are tightly secured, over-tightening your valves can result in connection deformities. These deformities can produce gaps and cracks, which result in leaks.
- ERROR: Incorrect Pressure Class: Valves should be selected to meet the required design pressure of the process. Failure to do this may lead to a plant breakdown. This is especially important when selecting safety relief valves.
- ERROR: Unawareness of flow direction. Understanding the valve’s flow direction will allow you to apply them properly. Even bi-directional instruments such as butterfly valves have a preferred flow direction, so reading up on your valve’s specifications will allow for a more effective installation.
