Accepted Answer

This valve is typically made from CW614N brass, which provides durability and resistance to corrosion. The internal components often include a solid wedge disc and packing rings for effective sealing.

Question 4

What are the pressure and temperature ratings for this valve?

Accepted Answer

The 1 1/4" brass gate valve can withstand a working pressure of up to 200 WOG (Water, Oil, Gas) and a steam pressure of 125 WSP. It is also rated for temperatures up to 130°C.

Question 5

How does the operation of a brass gate valve work?

Accepted Answer

The valve operates by turning the handwheel, which moves the stem connected to the disc. A few turns of the wheel will either raise the disc to open the flow or lower it to close off the pipeline completely.

Question 6

Is this valve suitable for potable water applications?

Accepted Answer

Generally, many brass gate valves are not intended for potable water applications due to potential lead content. It's essential to verify that any specific product is labeled as lead-free if intended for drinking water use.

The 1 1/4" brass gate valve typically features female threaded connections compatible with both NPT (National Pipe Thread) and BSP (British Standard Pipe) standards, allowing for versatile installation options.

Question 8

Can this valve be operated in tight spaces?

Accepted Answer

Yes, the non-rising stem design allows the valve to be operated in confined spaces without requiring additional vertical clearance, making it ideal for installations where space is limited.

Question 9

How can I ensure proper sealing and maintenance of this valve?

Accepted Answer

Regularly check the packing nut for tightness and inspect for any leaks around the stem area. If necessary, adjustments can be made using an adjustable packing nut to maintain optimal sealing performance.
