Product Description


what is Flanged x Grooved End Resilient Wedge NRS Gate Valve Z485 ? What is the connect Standard of Flanged x Grooved End Resilient Wedge NRS Gate Valve Z485 ?

Flange x Grooved End Resilient Wedge NRS (non rising Stem) Gate Valve Z485 is a special type of gate valve designed for versatile installation in piping systems. Let’s break down its main features and explore connectivity standards:

Flange x recessed end resilient wedge NRS gate valve Z485:
Flange end:

The valve has a flange on one end that allows for a secure bolted connection to the pipe using a flange connection. Flanges are common in various industries due to their stability and reliability.
Groove end:

The other end of the valve has a grooved end that allows for quick and efficient installation using a grooved fitting. Groove connections are known for their ease of installation and flexibility.
Elastic wedge:

The valve uses a resilient wedge, usually made of a material such as rubber or EPDM. This design ensures a tight seal even if debris or sediment is present in the pipe.
NRS (non rising stem ):

The concealed stem design means the valve’s stem does not move vertically during operation. Instead, the gate moves up and down to control flow.
Connection standards:
Specific connection standards for flange x grooved end resilient wedge NRS gate valve Z485 may vary depending on the manufacturer and the intended application. However, common standards that may be relevant to this type of valve include:

Flange connection standard:

ANSI/ASME B16.1: Standard for cast iron pipe flanges and flange accessories.
ANSI/ASME B16.5: Standard for Pipe Flanges and Flange Fittings.
Grooved connection standards:

AWWA C606: Standard for Groove and Shoulder Joints.
ASTM A536: Standard Specification for Ductile Iron Castings.
Material standards:

ASTM standards for materials used in valve construction, such as ASTM A126 for gray iron castings or ASTM A536 for ductile iron castings.
Notably, the valve complies with industry standards, ensuring its reliability and compatibility in piping systems. The manufacturer will provide specific standards related to the flange x grooved end resilient wedge NRS gate valve Z485 in their product documentation. When installing and maintaining gate valves in piping systems, always refer to the manufacturer’s guidelines and comply with local codes and standards.
