Webstone Valve 44444WPR Isolator Valve 1" W/Relief Valve Lead Free

Webstone Valve 44444WPR

Cash Acme VR-801 VAC uum relief valve is designed to protect hot water supply systems and pressure vessels against negative pressure. It is especially well suited for many domestic and commercial systems. It works by preventing internal VAC uum conditions that could result in burned out heaters and/or collapsed storage tanks. Installed on the cold water supply line, the Cash Acme VR-801 closes tightly under pressure and opens at a 1" mercury VAC uum. Atmosphere admitted to the system breaks the VAC uum, preventing collapse of the storage tank.,

Watts Regulators series LF3L and LF53L are used for protection against excessive pressure on domestic storage tanks or tankless water heaters. Similar in construction to Watts model LF10L, the model LF3L has no temperature relieving element. Model LF53L has the same basic design as model LF3L except it is furnished in 1/2" size and does not comply with ASME requirements. Pressure range is 75 - 150 psi. Series LF3L and LF53L come in standard settings of 75, 100, 125 and 150 psi. These pressure relief valves are popularly used in conjunction with the model LF210 gas shutoff valve on gas water heaters to shut off gas to heater if water heater temperature exceeds 210 deg F. The LF3L and LF53L features lead free construction to comply with lead free installation requirements.

• Relieves excessive pressure on storage tanks
• Relieves excessive pressure on tankless water heaters
• Compatible with model LF210 gas shut-off valves
