Z15X-16Q Threaded Soft Gate Valve

The Threaded Soft Gate Valve operates via a handwheel-driven rising stem, offering easy installation with threaded connections (DN15-DN50). Its soft seal ensures low leakage for water/gas in low-pressure systems, with bidirectional flow and max 16 bar pressure, suitable for civil and industrial applications.

PRODUCT DESCRIPTION

1.By rotating the handwheel the valve stem moves vertically driving the gate to rise or fall
2.Open: The gate rises to the top of the valve cavity, the fluid channel is fully opened, and the resistance is small.
3.Close: The gate is pressed down to the valve seat, and the soft sealing surface is in close contact with the valve seat, blocking the fluid.

FEATURES

1.Threaded connection (thread): easy to install, no welding required, suitable for small-diameter pipes (such as DN15-DN50).
2.Soft seal design: elastic material seal, low leakage rate, especially suitable for water, gas and other normal temperature and low-pressure media.
3.Low flow resistance: straight flow channel when fully open, small pressure loss.
4.Bidirectional flow: symmetrical gate structure allows bidirectional flow of fluid.
5.Limitations: generally not resistant to high temperature and high pressure, frequent operation can easily wear the sealing surface.

APPLICATION

1.Civilian field: building water supply and drainage, HVAC system (heating, air conditioning).
2.Industrial field: low-pressure water pipes, fire protection pipes, low-pressure gas transmission.
3.Special media: suitable for non-corrosive or weakly corrosive media such as clean water, oil, and gas.

WORKING PRESSURE

Maximum working pressure 16 bar (230psi).

STANDARD

1.Product testing is carried out in accordance with GB/T13927 Industrial valve pressure test.
2.The threaded connection is manufactured according to JB/T7307-89 (pipe thread without thread seal).
