STORZ Hydrant Landing Valve RG / BSP Female Inlet

Description

A STORZ hydrant landing valve in brass, signal red finish, with Roll Groove / BSP Female inlet. The valve connects a building’s fire main to the fire brigade attack hose via a Storz 65mm outlet coupling — the standard used by Fire and Rescue NSW (FRNSW) and specified in many commercial and industrial building fire systems. Roll Groove inlet suits 80mm grooved pipe; BSP Female inlet suits 65mm BSP threaded pipe. Includes a plastic blanking cap and a Forged Aluminium Alloy NEN 3374 Storz adaptor.

The landing valve is the interface between the building’s fixed fire main and the fire brigade. Installed in a cabinet or on a wall at the fire hydrant point, it allows fire brigade personnel to connect attack hoses without requiring any pipe modification at the point of connection. The STORZ outlet coupling is the correct specification for FRNSW and for any building where Storz coupling is nominated in the design specification.

Key Features

• Storz 65mm outlet coupling — Forged Aluminium Alloy NEN 3374 Storz adaptor complying with FRNSW requirements

• Brass construction — durable, corrosion-resistant material for long-term installation in building fire mains
• Signal red finish — standard colour identification for fire fighting equipment
• Plastic blanking cap included — protects the outlet coupling between inspections and testing

Compliance & Installation

Hydrant landing valves are installed as part of a building’s fire hydrant system in accordance with AS 2419.1 (Fire hydrant installations — system design, installation and commissioning). Installation must be carried out by a licensed fire protection contractor. The valve must be accessible to the fire brigade and located in accordance with AS 2419.1 and the relevant building approval. Confirm the outlet coupling standard with the local fire authority or FCC for the building before ordering — coupling specifications vary by jurisdiction.

Frequently Asked Questions

Where This Landing Valve Is Used

• Commercial buildings with an internal fire hydrant system requiring FRNSW-compatible Storz outlet
• Industrial facilities and warehouses with Storz coupling specification
• Multi-storey buildings with fire main risers connecting landing valve points on each floor
• Buildings where the Agreed Technical Requirements or FCC specification nominate Storz coupling
• Replacement of existing Storz-outlet landing valves in building fire main upgrades

What is the difference between Roll Groove and BSP Male inlet landing valves?

The inlet connection refers to how the landing valve connects to the building’s fire main pipe. A Roll Groove (RG) inlet connects to a mechanically grooved pipe — the pipe is grooved at the end and a coupling such as a Victaulic fitting clamps around the groove. This suits modern fire main installations using grooved mechanical joints. A BSP Female inlet connects to a BSP Male threaded pipe, which is the standard in older or threaded-pipe installations. Both inlet types have the same outlet — the difference is only in how they connect to the building’s pipe network. Choose the type that matches your existing pipe system.

What is a Storz coupling and which fire brigades use it?

Storz coupling is a symmetrical interlocking coupling system — the two halves are identical and connect by rotating quarter-turn. Storz 65mm is the standard outlet coupling used by Fire and Rescue NSW (FRNSW) and is specified in many commercial and industrial building fire systems in NSW. The Forged Aluminium Alloy NEN 3374 Storz coupling complies with the Dutch standard for Storz couplings and meets FRNSW specifications. If your building is in NSW or is designed to an FRNSW-compatible specification, the STORZ landing valve is the correct outlet type.

What does the NEN 3374 standard refer to?

NEN 3374 is the Dutch (Netherlands Normalisatie-instituut) standard for Storz couplings, which defines the dimensions and tolerances for the Storz interlocking coupling system. Australian fire authorities that use Storz couplings reference this standard for coupling compatibility. A coupling that complies with NEN 3374 will connect correctly with the fire brigade’s Storz attack hose fittings. This compliance reference appears on the Flamestop TDS for this product and confirms the coupling meets the dimensional standard required for FRNSW use.

Is the blanking cap supplied with the valve important?

Yes — the blanking cap protects the outlet coupling from debris, dirt, and physical damage between inspections and use. AS 2419.1 requires that hydrant outlets be protected. The plastic blanking cap supplied with this valve is suitable for routine protection. For high-security or vandalism-prone locations, a brass blanking cap or a G-Lock securing device may be appropriate. If the blanking cap is damaged, cracked or missing, replace it at the next service — an unprotected outlet can collect debris that prevents the fire brigade from making a clean connection quickly in an emergency.

Can I install this valve myself?

No — installation of components in a building fire hydrant system must be carried out by a licensed fire protection contractor. The system must be commissioned and tested in accordance with AS 2419.1, and the completed installation must be inspected by the relevant building certifier or fire authority as required by the building approval. Ongoing inspection and maintenance is required under AS 1851. If you are replacing an existing valve on an existing system, the work still constitutes a modification to the fire protection system and requires a licensed contractor.
