What are the 7 types of valves?
Valves are vital part of any pipe work, and it is used to control, direct, or regulate the flow of fluid (liquid or gas). There are many types of valves specialized designs. However the majority are one of the following 7 main types acting as either a Gate valve, Globe Valve, Ball valve, Check valve, Butterfly valve, Plug valve or a Actuated valve. This article focuses on these key types, incorporating specific product examples to show the applications in water supply, gas systems and industrial processes.
Valve gate valves are used in a linear motion, are they usually used for shut off service and they provide very low resistance to flow when they are fully open. Globe valves are well suited for throttling as well as regulating flow as the flow rate can be controlled very precisely by the design of Globe valves. Ball valves use a spherical disc with a bore that can also provide a reliable sealing and fast shut-off options. Plug valves - same principle as ball valves, but with conical or cylindrical plug, ideal for application, when you need to quickly open/close.
Check valves are the most important for the prevention of backflow and the maintenance of flow in one direction within any system. Among your products are many high tech types of this kind. Dual Plate Flange Type Check Valve- designed as a space saver to meet line size requirements. In the same way, the Light Weight Dual Plate wafer check valve is space saving in tight space applications. The Water Supply Wafer Check Valve is specially designed for potable water in municipal and utilities applications. Improved life and enhanced corrosion resistance are presented in Full Rubber Coated Check Valve and theRubber Coated Flanged Type Check Valve which act as the barrier against chemical and abrasive damages. And the Ductile Iron PTFE Coated Check Valve also offers a great combination of durability and corrosion protection. When it comes to controlling noise and water hammer, Cast Iron Silent Check Valve, Flanged Ductile Iron Silent Check Valve, Water Supply Silent Check Valve and Gas Supply Silent Check Valve play vital roles in the system stability.
The fifth foremost styling is that of butterfly valves are compact and fast operating. These valves consist of a rotating disc that is used to control flow and have broad application in pipelines of large diameter. The Wafer Type Butterfly Valve, Stainless Steel Butterfly Valve, Keystone Butterfly Valves, Lug Style Butterfly Valve, High Performance Butterfly Valves, Motorized Butterfly Valve, Flanged Butterfly Valve, Lug Butterfly Valve etc. for all a range of pressure ratings (‘psi’), installation needs and environmental conditions including from clean Stainless Steel designs for hygienic applications in the food industries right through to heavily burdened industrial applications facilities.
In essence, actuated valves are the high-tech version of valve mechanics. The Electric Valve Actuator and the Butterfly Valve Actuator are products that convert manual valves into automated control elements that can be remotely operated, finely modulated and connected to the Smart Control System. This automation is essential to modern infrastructure where efficiency, safety and real-time monitoring are at the top of the list.
So, having a good understanding of these seven core valve types — and their available product options — is vital for ensuring you pick the right part for any hydraulic or pneumatic system. From the need to control backflow, or pressure regulation, to complex processing and automation, the right valve can provide operational reliability and enduring performance.
