Gate Valve Class 150 WCB
Designed for a pressure rating of 150 psi (pounds per square inch) and constructed from WCB, which stands for Weldable Cast Carbon Steel. This type of valve is used to start or stop fluid flow in a pipeline but is not intended for flow regulation.
Component
1. Gate Valve
A gate valve is one of the most commonly used valves for isolating fluid flow in a pipeline. Its main function is to fully open or fully close the flow path (not to throttle or control the flow rate). Partial opening can cause turbulence, vibration, and damage to the valve.
2. Class 150
The "Class 150" refers to the maximum working pressure the valve can withstand, which in this case is 150 psi (approximately 10.3 bar), based on ASME/ANSI B16.5 standards.
3. WCB (Weldable Cast Carbon Steel)
WCB is a type of cast carbon steel (ASTM A216 Grade WCB) commonly used for valve bodies. It is weldable, strong, and durable, making it suitable for medium-pressure and moderate-temperature applications.
Function
The primary function of a Gate Valve Class 150 WCB is to open and close the flow of fluids in piping systems. It is not suitable for throttling, as this may lead to flow disturbance and wear inside the valve.
Common Applications
This valve is widely used in various industries for low to medium pressure systems, such as:
- Water distribution
- Oil and gas
- Chemical and petrochemical plants
- HVAC systems
- General-purpose fluid handling
