Series SS07F Stainless Steel Single Detector Check Valves
SIZE RANGE: 4" through 10".
Series SS07F Stainless Steel Single Detector Check Valves are designed to detect any leakage or unauthorized use of water from fire sprinkler systems. During times of minimal water flow, the valve clapper remains closed so that the water flows through a bypass meter (optional). When fire flow is required, the increased demand will open the clapper to allow full flow..
Features
• Lightest weight in the industry - reduces shipping and handling costs.
• Non-corrosive stainless steel construction - eliminates pin holes and voids associated with epoxy coated valves.
• Can be installed in horizontal/vertical positions.
• Optional meter bypass assembly (specify GPM or CFM).Required to detect leakage or theft of water.
• Optional sized bypass tappings available.

Series 800M4QTAnti-Siphon PressureVacuum Breakers
SIZE RANGE: 1/2" through 2".
Series 800M4QT is designed to prevent back-siphonage of contaminated water into a potable water supply. The valve is ideally suitable for irrigation systems, industrial process water systems and other continuous pressure piping system applications where the water enters the equipment at or below its flood rim. The disc float and check valve are suitable for temperatures up to 140°F. The resilient sealing float o-ring and seal check disc are silicone rubber which is resistant to heat, shock and chemical attack.

Series 288A Atmospheric Vacuum Breakers
SIZE RANGE: ¼" through 3".
Series 288A represent a complete line of vacuum breakers designed to prevent back-siphonage of contaminated water into a potable water supply. They are ideally recommended for low flow installations. They also contain a durable silicone disc which has high heat and water hammer shock resistance and assures tight seating with the lightest of seating contact.

Calibrated & Preset Pressure Relief Valves for Fire Protection Systems
SIZE RANGE: 1/2"-3/4"
Calibrated Pressure Relief Valve is spring operated bronze relief valves designed to be used only as protection from the build up of excessive pressure in systems containing water, oil or air. Series BPR050C is not an ASME approved safety relief valve and should not be used in system applications with this requirement. This series also incorporates a calibrated adjustment feature for setting the valve to the relief pressure required.
