Questions about this item

How does the 175 psi pressure rating affect long-term reliability under sustained load?

The valve body is rated for a maximum water pressure of 175 psi. Exceeding this limit under continuous operation can accelerate wear on the bronze body and FKM liner, potentially leading to leaks or seal failure over time.

What temperature rise should I expect at the handle during all-day operation near the 275 °F limit?

With a fluid temperature range up to 275 °F, the bronze body and lever handle will conduct significant heat. The handle can become too hot to touch safely without insulation or protective gloves during extended high-temperature service.

Which pipe preparation and solder alloy are required for the 1/2 in solder end connections?

The valve features 1/2 inch solder ends designed for copper tubing. Joints must be cleaned, fluxed and made with a lead-free solder alloy suitable for potable water and the 30–275 °F service temperature range.
