Maxitrol GV gas valves are combination control systems featuring several integrated and optional components. The electronic system for gas appliances provides remote operation and safety features for managing gas flow and ignition in appliances like fireplaces and commercial cooking equipment.The specific components of the GV30/GV30A and GV60 series can be varied depending on the inclusion of optional features to enhance operation.The Maxitrol GV system integrates both mechanical safety features (like the flame supervision device) within the valve and electronic components (handset, receiver) for convenient, remote control operation of gas appliances.

Keeflex hoses are a range of stainless steel braided gas hoses and S-core gas hoses primarily used for Natural Gas & LPG applications, known for their industrial durability, flexibility and safety in gas transfer applications. The stainless steel S-core design and stainless steel braiding construction offers industrial durability, excellent resistance to wear under vibration (ideal for off-road or mobile applications) and sufficient flexibility for easy installation.Keeflex hoses are primarily used for gas connections, including pigtail hoses for LPG cylinders and connecting gas appliances. They are available with various fittings, including POL handwheel connections, 1/4" NPT male inverted flare, 7/16" UNS and the newer LCC27 "Safe Lok" fittings, which are gradually replacing POL fittings in Victoria.The hoses are designed and approved for use in applications such as Commercial Kitchens, BBQs and Caravan Gas systems. Safety and Standards: The hoses are manufactured to comply with Australian standards (e.g., AGA Approved No. AGA 8258G, AS/NZS1869 Class F) and have a pressure rating of 2600 kPa.

Keefer Brothers offers a comprehensive range of burners and related accessories, primarily for commercial, industrial, and specialized applications like wok cooking, pottery kilns, and glasshouses. High-performance jet burners with multiple nozzles designed for intense heat, suitable for commercial wok ranges are available in both LPG and natural gas options.Keefer Bros also manufactures replacement burners specifically designed to fit Waldorf/Comcater and similar commercial catering equipment ranges, including top, grill, and oven burners.Our Infra-Red Burners for toaster/salamander units and vertical/rotisserie applications, provide radiant heat while our Aeration Burners designed for industrial use, incorporate air mixture control for specific applications. In addition to the main burners, Keefer Bros provides a wide array of associated accessories such as Brass Injectors, cast and disc-type air shutters, Wok rings and specific fittings for Wok set ups. Trivets and Pot Stands including stainless steel pot stands and pot holders and various pilot burner options and components are on hand for use with our range of burners.A full range of Gas Connectors, Hoses and Couplings are available to cover all requirements of your set up.

Keefer Brothers offers manual and automatic butterfly valves and adjustable flow valves for commercial and industrial applications where an operator can physically open, close, or throttle the flow. Our AN Nozzles are used to control and direct gas flow in Keefer's range of high-capacity burners for commercial cooking equipment (like Mongolian woks) and industrial kilns. We also provide gas inspirators (also known as Venturis) to accurately mix gas and atmospheric air in the correct proportions before combustion in high-heat applications like kilns or commercial burners.Keefer flame retention heads provide stable combustion and prevent the flame from lifting off the burner port or flashing back into the mixer (inspirator) tube. This ensures efficient and safe operation of high-performance burners while our limited orifice valves offer adjustable precise flow control to fine-tune the gas flow to individual burners in a multi-burner system.With safety a priority the Keegas Gas Check kit is a comprehensive gas pressure proving and shut-off system designed for commercial and industrial applications to automatically detect leaks and ensure gas tightness before allowing the supply to operate. The system is designed to meet Australian Standard AS/NZS 5601.1 requirements and automatically performs a check at start-up to ensure all downstream valves are closed and the pipework is gas-tight. This is particularly important for high-risk environments like commercial kitchens, schools, and factories. Keefer supplies emergency stop buttons as an essential safety accessory for their gas safety systems.

Keefer Brothers manufactures a variety of their own brand of gas valves and associated controls, primarily designed for durability and specific for commercial/industrial use.Our "A" Series Gas Taps and "B" Servies Valves are core product lines for general control of gas flow. The Safety-oriented Flame Failure Gas Cocks are designed to automatically shut off gas if the flame goes out. Our high grade laboratory cocks offer precise gas control in educational, scientific, and industrial environments. Manufactured from dezincification-resistant (DR) brass they are designed to meet the stringent quality requirements for their conditions.We stock a range incorporating Single Outlet Straight Valves, Twin Outlet 180° Straight Valves (for dual-outlet turret valve where the outlets face opposite directions), Twin Outlet 90° Straight Valves (for dual-outlet turret valve with outlets at a 90-degree angle) and a Twin Outlet 90° Left/Right Hand Valve.All Keefer Valves and Gas Cocks comply with rigorous quality and safety requirements as stipulated by the Australian Gas Association (AGA)

Keefer Brothers (Aust) Pty Ltd is a supplier and manufacturer of gas-related products for the "Pottery Kiln & Glasshouse" industry, offering the specialized burners and accessories required for precise temperature control and robust, high-capacity gas supply systems.Our AM-Series Pottery Kiln Burners are complete with self-contained burner units featuring a patented 2-stage injector that allows for full flame control (oxidizing to reducing) via a slide air shutter. It features a flame failure valve, control valve, separated controlled pilot, and mounting bracket.Available in various sizes, such as AM50 (47mj), AM100 (158mj), and AM200 (475mj) at 70kPa pressure. The pilot enables a slow heat rise to dry green ware and is necessary for fibre kilns where heat can rise too quickly. Keefer also supplies the various related components for gas installations in these demanding environments such as pressure gauges and connectors.
