Frequently Asked Questions

What media are suitable for the GL41W / G41W valve series?

These valves are designed to handle a wide range of media, including water, steam, oil, and nitric acid corrosive liquids, making them versatile for industrial and fluid control applications.

What is the maximum operating temperature for these valves?

The GL41W-16P supports temperatures up to ≤150°C, while the high-temperature model GL41F-25P can withstand operating temperatures up to ≤425°C.

What is the pressure rating difference between 16P and 25P models?

The 16P models feature a nominal pressure rating of 1.6 MPa (with a water strength test pressure of 2.4 MPa), whereas the 25P models are rated for a higher pressure of 2.5 MPa (with a water strength test pressure of 3.8 MPa).

What size ranges are available for the G41W series?

The G41W series covers nominal diameters ranging from DN15 (15mm) up to DN200 (200mm), accommodating various piping configurations and flow capacities.

What does "number of nets" indicate in the specification chart?

The "number of nets" refers to the mesh or screen density inside the strainer element. Smaller diameter valves typically utilize higher mesh counts (e.g., 12 nets for DN15-DN50) for finer filtration, while larger diameters use lower mesh counts (e.g., 6 nets for DN150-DN200) to maintain adequate flow rate.
