ARV Vacuum Breaker
Air vent- Pressure
- Rated 150 psi; operating 1.5–150 psi
- Connection
- Acetal (POM) body
- Sizes
- Male threaded 1/2" (DN12)
- Best for
- The smallest vacuum breaker Bermad make — 1/2" for the end of a lateral or a single riser, where a full kinetic valve is more than the line needs
Catalog ↗K10 Kinetic Air Valve
Air vent- Pressure
- Rated 150 psi; operating 1.5–150 psi
- Connection
- Male threaded; glass-reinforced nylon body
- Sizes
- Male threaded 3/4"–2" (DN20–50)
- Best for
- Large-orifice valve for filling and draining — it dumps the air ahead of the water on start-up and lets air back in on shutdown so the pipe cannot collapse under vacuum. It does not bleed air during operation; pair it with an automatic valve or use a C10 combination if you need both
Catalog ↗A10 Automatic Air Valve
Air vent- Pressure
- Rated 150 or 175 psi; opens from 0.1 bar (1.5 psi)
- Connection
- Male threaded, sideways outlet; glass-reinforced nylon body, PBT automatic orifice
- Sizes
- Male threaded 3/4"–1" (DN20–25); optional 3/4" female threaded outlet for retrofit
- Best for
- Bleeds the air that keeps accumulating at high points while the system is running under pressure. Trapped air is what quietly adds head loss and cuts flow, and a kinetic valve will not touch it — this is the one that does. Female-threaded outlet option lets it retrofit onto an existing riser
Catalog ↗A30 Automatic Air Valve
Air vent- Connection
- Sideways outlet; glass-reinforced nylon body, PBT automatic orifice
- Sizes
- Male threaded 3/4"–1" (DN20–25); optional 3/4" female threaded outlet for retrofit
- Best for
- Continuous air release like the A10, with a service port (code P) that takes a 1/8" plug for a pressure gauge and a snap-on 90° elbow for a 3/4" connection — so you can gauge the high point without breaking into the line
Catalog ↗C10 Combination Air Valve
Air vent- Pressure
- Opens from 0.1 bar (1.5 psi)
- Connection
- Straight-flow body with equal inlet and outlet size; threaded side outlet on the 2" for surge protection
- Sizes
- Threaded 3/4"–1" (DN20–25) and 2" (DN50)
- Best for
- Kinetic and automatic action in one valve. Surge Protection (code SP) partially closes the kinetic orifice so air discharges slower and the water column does not slam into the closing float — the usual cause of a burst on pump start. Assisted Closing (code AC) available
Catalog ↗C15 Combination Air Valve
Air vent- Pressure
- Rated 150 or 175 psi
- Connection
- Glass-reinforced nylon body; polypropylene and glass-reinforced nylon float
- Sizes
- Male threaded 2" (DN50) inlet, sideways female threaded 1.5" (DN40) outlet
- Best for
- Straight-flow body passes higher air flow rates than a standard combination valve of the same size — for filling a big submain quickly. Service port takes a 1/4" plug for a pressure gauge
Catalog ↗C30 Combination Air Valve
Air vent- Connection
- Straight-flow body with equal inlet and outlet; extension with downwards outlet on the 2"
- Sizes
- Threaded 1" (DN25) and 2" (DN50)
- Best for
- Surge protection is standard on the 2" — the kinetic orifice partially closes during the second stage of air discharge, so the water column decelerates instead of slamming the float shut. That slam is what splits pipe on pump start. Service ports for a gauge
Catalog ↗C35 Combination Air Valve
Air vent- Pressure
- Rated 230 psi — the highest in the Bermad plastic air valve range
- Connection
- Glass-reinforced nylon body; polypropylene and glass-reinforced nylon float
- Sizes
- Male threaded 2" (DN50) inlet, sideways female threaded 1.5" (DN40) outlet
- Best for
- Same straight-flow high-capacity design as the C15 but rated to 230 psi, for pump discharge and high-head mains where a 150 psi valve is not enough
Catalog ↗C70 Combination Air Valve
Air vent- Connection
- Straight-flow body with equal inlet and outlet size; three outlet options — sideways, downwards, or circular mushroom surround
- Best for
- Three outlet configurations from one valve: the mushroom surround discharges evenly all round, the downwards outlet keeps discharged water off the equipment below, and sideways suits a tight pit. Service ports for a pressure gauge
