MT 40942020 Water Valve 3/4 inch MF with Short Handle

The MT 40942020 is a professional-grade 3/4 inch water valve designed for precise flow control in residential and commercial plumbing systems. Featuring a male-female (MF) connection and a space-saving short handle, this valve provides a reliable solution for managing water supply in various piping configurations. Its robust build quality ensures durability and consistent performance, even in demanding environments where long-term reliability is essential.

Advantages

The primary benefit of this valve is its compact design, which allows for installation in tight spaces where standard valves with long handles might not fit. The male-female threaded connection simplifies the integration process into existing plumbing lines, reducing the need for additional adapters. Constructed from high-quality materials, the valve offers excellent resistance to wear and corrosion, ensuring a secure seal and smooth operation over its entire service life.

Suitable for

• Residential water supply installations
• Commercial plumbing systems
• Tight-space piping configurations
• Isolation of water flow for maintenance

When it may not be suitable

This valve is not intended for use in high-pressure industrial steam systems or applications involving aggressive chemicals that may degrade the internal seals. It is also not suitable for installations requiring automated or motorized valve control.

Key specifications

• Connection size: 3/4 inch
• Connection type: Male-Female (MF)
• Handle type: Short handle
• Application: Water supply systems

How to use

To install the valve, ensure the water supply is completely shut off and the pipes are drained. Apply appropriate thread sealant or PTFE tape to the male threads to ensure a leak-proof connection. Thread the valve onto the pipe fitting and tighten it using a suitable wrench, taking care not to overtighten and damage the threads. Once installed, turn the short handle to the open or closed position to control the water flow as needed.

What to consider before purchase

• Verify that the 3/4 inch size matches your existing pipe diameter.
• Ensure there is sufficient clearance to rotate the short handle.
• Check that the male-female configuration aligns with your current plumbing layout.

Usage recommendations

Regularly inspect the valve for signs of leakage or stiffness in the handle. It is recommended to operate the valve at least once every few months to prevent mineral buildup and ensure the internal mechanism remains free-moving.
