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.,

Resideo Braukmann DS06 Dial Set Pressure Regulating Valve is a high quality pressure regulating valve that maintains a constant outlet pressure over a wide range of inlet supply pressures. It is suitable for potable water and irrigation applications. The downstream pressure adjustment dial eliminates the need for a pressure gauge when adjusting the pressure setting (static pressure only).

• Built-In Dial-Set- no gauge is needed to install or set static pressure
• Built-in strainer to simplify maintenance
• Fabric reinforced diaphragm regulator, stainless steel and engineered thermoplastics internal parts
• Balanced single seat construction
• Minimum pressure differential between inlet and outlet ports is 14.5 psig
• Plus or minus 4 psig dial calibration
• Less than 0.25% of weighted average of low lead content
• 1/4" NPT gauge tap
• 10:1 maximum reduction ratio
• Double union sweat union fittings

All field vent hoods are made of heavy gauge aluminum and can be used with natural gas, LP gas or oil-fired equipment. There are five diameters ranging from 3 to 8 Inch. The concentric pipe, angled outlet deflectors, and spaced plate design allow for better heat dissipation. This type of construction minimizes the effects of heat on the outside wall. The angled hood design reduces the effects of wind on the venting system. The inner and outer pipe are a continuous structure. This allows for easy installation to power venter or vent pipe and also eliminates possible positive pressure leaks in the wall section.

• Can be used in conjunction with PVG and PVO power venters or with forced draft systems
• 7-5/8 x 7-5/8 shield for 0 clearance to combustible
• Designed for standard vent pipe and Class B type double-wall (B-Vent) connection
• Provides proper clearance between flue gas stream and wall combustible
