Features and Applications of Globe Valves

图片
Conventional globe valves may be used for isolation and throttling services. Although these valves exhibit slightly higher pressure drops than straight- through valves (e.g., gate, plug, ball, etc.), they may be used where the pressure drop through the valve is not a controlling factor. Globe valves  are extensively employed to control flow. The range of flow control, pressure drop, and duty must be considered in the design of the valve to avert premature failure and to assure satisfactory service. Valves subjected to high-differential pressure-throttling service require specially designed valve trim. Generally the maximum differential pressure across the valve disc should not exceed 20 percent of the maximum upstream pressure or 200 psi (1380 kPa), whichever is less. Valves with special trim may be designed for applications exceeding these differential pressure limits.   Forged steel A105 Globe valve socket flange end   Types of Globe Valves Tee Pattern globe valves have the lowest co

Types of Butterfly Valves and Their Functions

图片
Butterfly valves are versatile flow control devices widely used in various industries. They are available in different types, each designed to meet specific application requirements. Understanding the various types of butterfly valves and their functions can help in selecting the most suitable valve for a particular system. Let's explore the different   types of butterfly valves   and their functions in more detail: Concentric Butterfly Valves: Concentric butterfly valves are the most common type and feature a resilient seat with a metal disc centered on the valve stem. They offer excellent sealing capabilities and are suitable for a wide range of applications, including HVAC systems, water treatment plants, and general industrial processes. The concentric design provides a tight shut-off, and the resilient seat ensures reliable sealing even in low-pressure applications. Double Offset Butterfly Valves: Double offset butterfly valves have a slightly offset disc that enables a cam-li

Swing Check Valve vs. Check Valve

图片
Valves   are essential components of any piping system as they regulate the flow of fluids and gases. They come in various types, each designed for a specific purpose. Two common types of valves are the swing check valve and the check valve. In this article, we will explore the differences between these two valves and help you determine which one is best for your application. ​ Check Valve A  check valve  is a valve that allows fluid or gas to flow in only one direction. It has a closure element that opens and closes automatically in response to the pressure of the fluid or gas passing through the valve. When the fluid or gas flows in the correct direction, the closure element opens, allowing the fluid or gas to pass through the valve. When the fluid or gas tries to flow in the opposite direction, the closure element closes, preventing backflow. Check valves are commonly used in applications where backflow prevention is critical, such as in sewage systems, irrigation systems, and gas p
