PRODUCTS DETAILS:
what is the Flanged End Resilient Wedge NRS Gate Valve Z45 200PSI type ？
The Flange End Resilient Wedge NRS (Concealed Stem) Gate Valve Z45 rated to 200
PSI is a specific type of fire protection valve designed for use in a variety of
applications including water distribution and industrial processes. Let’s break
down the main features:
Flange End: The valve has a flange end that allows for a secure bolted connection
to the pipes in the piping system. Flanges are a common method of connecting
valves in water and industrial systems.
Resilient Wedges: Resilient wedge designs utilize flexible wedges made of
materials such as rubber or EPDM. This design helps the valve maintain a tight
seal even if debris or sediment is present in the pipe.
NRS (non-rising stem): Indicates that the valve stem does not rise when the valve
is opened. In a concealed stem gate valve, the valve stem remains in a fixed
position while the gate plate moves up and down to control the flow. This design
is often used in applications where space is limited.
200 PSI Rating: This valve is designed to handle a maximum pressure of 200 pounds
per square inch (PSI). This pressure rating represents the maximum pressure the
valve can withstand without failure.
Flange Ended Resilient Wedge NRS Gate Valve Type Z45 200PSI is commonly used in
water supply systems, wastewater treatment plants and a variety of industrial
processes where reliable flow control and sealing are critical.
It’s important to note that valve specifics, such as size, materials, and
compliance with industry standards, may vary depending on the manufacturer. If you
require detailed information on a specific Z45 valve, it is recommended to refer
to the product documentation provided by the manufacturer or contact them directly
for accurate specifications.
