Rain Bird 100HVMB 1-Inch Male x Barb Valve

Rain Bird 100HVMB 1-Inch Male x Barb Valve

Brand: Rain Bird | SKU: 100HVMB

Product Overview

Choose the Rain Bird 100HVMB when a sprinkler zone needs a 1-inch male-threaded connection at one end and a barb connection for polyethylene pipe at the other. Its MB body is longer than the standard HV body, so check the 5.68-inch length against the existing manifold. This is the standard HV version without the HVF flow-adjustment stem.

Key Features

• Connection layout: 1-inch male NPT x barb.
• Standard HV model without an HVF adjustment stem.
• Eccentric diaphragm supports smooth closing.
• Four-screw bonnet access and two manual-bleed options.

Common Uses

• Controlling a residential sprinkler zone.
• Replacing a matching male-threaded x barb valve on a polyethylene-pipe zone.

Compatibility & Installation Notes

Match both connection styles and the direction arrow before replacing a valve. Flush the supply line before assembly and keep the solenoid on the downstream side.

Use the manufacturer’s thread-sealing instructions on the male NPT end. Seat compatible polyethylene pipe fully over the barb and secure it with suitable clamps; confirm the pipe fits the nominal 1-inch connection.

Use waterproof irrigation wire connectors and a compatible 24 VAC controller. Size wire for the run and electrical load.

Install a 200-mesh filter upstream for flow below 3 GPM or any landscape drip application. Provide separate pressure regulation and backflow protection as the system and local requirements demand.

Use the solenoid for internal manual bleed and the external bleed screw for flushing. Manual opening through the bleed does not add an HVF flow-control function.

Frequently Asked Questions

What does MB mean on 100HVMB?

MB identifies the male-threaded x barb connection layout. Match both ends and the flow arrow to the existing pipework.

Does it include flow control?

No. 100HVMB is the standard HV model without the dedicated flow-adjustment stem found on HVF models.

What controller power does it need?

The supplied solenoid requires 24 VAC, 50/60 Hz. Use waterproof wire connections and check the controller and wire sizing.

Can it operate a drip zone?

Yes, within its operating range. Rain Bird requires a 200-mesh upstream filter for any landscape drip application; provide pressure regulation appropriate to the emitters.

Why Buy from Big Frog Supply?

Choose 100HVMB when the replacement must bridge a male NPT connection and clamped polyethylene pipe without changing to a slip-body valve. Its 5.68-inch MB length matters for manifold spacing, and its standard HV design suits zones that do not need an HVF adjustment stem. Match both pipe ends before choosing by nominal size alone.
