Watts Regulators series 174A boiler pressure relief valves are used in hot water heating and domestic supply boiler applications to protect against excessive pressures on all types of hot water heating supply boiler equipment. It consists of a bronze body construction with NPT threaded female inlet and NPT threaded female outlet (drain) connections, non-metallic disc-to-metal seating, stainless steel spring, and test lever. Series 174A resists corrosive water conditions, sticking and freezing, and prevents water and sediment from being trapped in the seat. It is designed for emergency safety relief and shall not be used as an operating control.

• Safety relief valves for pressure protection only of all types of hot water heating boiler equipment
• Seat located above drain, water can't be trapped and sediment can't foul seat
• Non-mechanical seat-to-disc alignment will not stick or freeze
• Water seal of high temperature resisting material isolates spring working parts from water during relief

• Offers constant water temperature under changing operating conditions
• Temperature is limited at any point and if cold water supply is interrupted, flow reduction occurs in seconds
• Designed to increase the amount of usable hot water
• Provides reliable performance at minimum flow of 0.5 gpm and proportional valve for simultaneous control of hot and cold
• Tamper-resistant design with nickel-plated brass construction and EPDM O-rings
• Designed for easy maintenance and Teflon coating prevents mineral build-up and extends life
• Lockable hand wheel for accurate temperature control
• Straight-through design (hot and cold at same level)
• Free thermostrip included to make temperature setting easy for one person to handle
• Designed for easy maintenance and element replacement
• Teflon coated brass shuttle, EPDM O-ring

Noisy pipes, valves, and other air-related noises are often accepted as the signs of a functioning system. Excessive pump noise, cavitation, and cascading in terminal units are considered normal. But air in system water can cause corrosion, reduced efficiency, poorly heated or inadequately cooled rooms, accelerated component wear and on-going complaints. There is a device that will keep your system free of air permanently. Less maintenance, quiet operation, fewer costs!. Unlike conventional air eliminators or air scoops, the Spirovent completely eliminates 100% of the free air, 100% of the entrained air, and up to 99.6% of the dissolved air in the system. Consisting of woven copper wire soldered to a copper tube, the patented Spirotube creates a low velocity area in the Spirovent that scrubs the bubbles from the water. The air bubbles rise and collect in the air chamber before they are vented from the system via an integral automatic valve. Air problems become a thing of the past.

• Maintenance free
• No venting required
• Vent head is designed to stay dry, dirt and leak resistant
• 1/2" male thread port for pressure testing or remote venting of unwanted gases
• Quiet operation
• Increased component life
• Reduced oxygen based corrosion and pump cavitation
• The automatic air vent is guaranteed not to leak and can only be closed by the installer for a pressure test
• The air chamber has been designed so that dirt cannot reach the valve
• Large capacity collection chamber reduces the need for frequent draining
• Drain valve for flushing out the dirt
• Brass vent head
• Non-ferrous float
• ViTon seal and o-ring
• Copper coalescing medium
