About TOHO — Taiwan-Made Bronze Valves
TOHO valves are manufactured in Taiwan and have built a reputation in the marine and industrial valve market for consistent quality bronze castings and practical, maintenance-friendly designs. The brand sits in a well-established segment of the market: bronze valves for utility service, offered at competitive pricing with reliable dimensional consistency that makes like-for-like replacements straightforward.
Taiwan's valve manufacturing sector has a long track record in bronze utility valves, with producers supplying the marine, building services, and industrial sectors across Asia and the Middle East for several decades. TOHO fits within this tradition — a no-frills, well-made bronze valve that delivers consistent performance in the service conditions it is designed for.
TOHO Valve Product Range
TOHO's core range covers the main bronze valve types used in marine utility and light industrial service. All are available in threaded (BSP/NPT) and flanged configurations across standard size ranges.
Bronze Gate Valve
TOHO bronze gate valves are the most commonly specified valve type in the range. Designed for full-bore, on/off isolation service, they are suitable for water, steam, and general utility applications. Rated to 150 psi steam working pressure (SWP) and 300 psi water, oil, and gas (W.O.G.), TOHO gate valves are available from ¼" through to 3" and 4" in threaded configuration, with flanged options across the standard size range. The body is sand-cast bronze with non-rising stem construction, and the packing is designed to be field-replaceable — a practical feature for marine maintenance teams.
Bronze Globe Valve
TOHO bronze globe valves are used where throttling or flow regulation is required alongside isolation. The globe valve's disc-against-seat design allows precise flow control in a way that a gate valve cannot, making them the preferred choice for steam service, bypass lines, and cooling water regulation. TOHO globe valves share the 150 psi SWP / 300 W.O.G. rating as the gate valve range and are available in sizes from ¼" to 4". They are commonly specified for HVAC, cooling systems, and marine utility service.
Bronze Swing Check Valve
TOHO swing check valves are used to prevent backflow in pipelines. The swing disc design makes them suitable for horizontal pipeline installation in water and non-viscous fluid service. Low pressure drop across the valve makes them appropriate for bilge, cooling, and general utility circuits where minimal system resistance is desirable.
Bronze Ball Valve
TOHO's bronze ball valve range (ST-600S series) provides quarter-turn isolation for water, air, and general utility service. Ball valves are preferred in applications where rapid on/off operation is required and where a full-bore, unobstructed flow path is important. They are frequently used in marine utility systems, building services, and light industrial settings where ease of operation and long service life with minimal maintenance are priorities.
Bronze Y-Strainer
TOHO also produces bronze Y-strainers (ST-002 series), used inline to remove particulates and protect downstream equipment such as pumps, control valves, and metering devices. Y-strainers are a standard requirement in seawater cooling systems and HVAC circuits, and complement the gate and globe valve range well — allowing procurement teams to source the strainer and associated isolation valves from the same brand and material family.
Bronze Safety Valve
The TOHO bronze safety valve with lever (L3-L series) provides pressure relief protection in steam and hot water systems. Safety valves are mandatory in pressurised systems and must be set to a calibrated relief pressure. TOHO's lever-operated safety valve is straightforward to test in service — an important consideration for maintenance-conscious operators.
Marine Applications for TOHO Valves
TOHO bronze valves are well-suited to a range of marine utility service applications on commercial vessels, workboats, and offshore support craft. Bronze is the material of choice for seawater-facing utility systems due to its inherent corrosion resistance in both fresh and salt water environments, without the cost premium of higher alloys.
Seawater cooling and HVAC circuits
Bronze gate and globe valves in the TOHO range are standard fits in seawater cooling circuits and HVAC systems aboard commercial vessels. Their corrosion resistance in salt water service, combined with ease of maintenance and packing replacement at sea, makes them practical choices for ship operators and repair teams. Ship repair yards in Singapore — including those operating under the Seatrium group at Tuas, Benoi, and Gul — regularly use bronze utility valves of this type for repair and replacement jobs across a wide range of vessel types.
Bilge and ballast systems
Bronze swing check valves are a common specification for bilge lines, where backflow prevention is essential. TOHO swing check valves in bronze provide reliable non-return function in these systems at a price point that makes ready-stock replacements practical for maintenance budgets. Y-strainers ahead of bilge pumps and overboard discharge valves are also standard system requirements that TOHO's range addresses.
General utility and domestic service
Beyond seawater and bilge circuits, TOHO bronze ball and gate valves are widely used in freshwater domestic systems, sanitary lines, and compressed air service aboard vessels. Their quarter-turn ball valve range is particularly convenient in confined spaces where a full-turn gate valve handwheel may be impractical.
Specifying TOHO Valves — What to Confirm Before Ordering
When placing an order for TOHO bronze valves through Aik Soon Hardware, confirm the following:
Valve type: Gate, globe, check, ball, Y-strainer, or safety valve. These are distinct products with different flow characteristics — confirm the correct type before ordering.
Size (nominal bore): Available across standard BSP sizes from ¼" upwards. State the nominal bore size required (e.g. ½", ¾", 1", 1¼", 1½", 2", 2½", 3").
End connection: Threaded (BSP or NPT) or flanged. Most TOHO utility valves are supplied in threaded configuration as standard; flanged versions are available for larger sizes.
Pressure rating: TOHO bronze valves are rated at 150 psi SWP and 300 W.O.G. Confirm your application's working pressure falls within this range. For higher-pressure marine service requiring JIS 10K, 16K, or 20K rated valves, other brands in Aik Soon's portfolio are more appropriate.
Note: TOHO bronze valves are dimensioned to BSP/ANSI pipe thread standards, not JIS flange face standards. If your application requires a JIS-rated flanged valve with a specific JIS figure number, Aik Soon's JIS-specific range (Showa, DK Valve, C&J, and others) would be the correct product family.
Frequently Asked Questions
What types of valves does TOHO manufacture?

TOHO bronze valves are used in marine utility service including seawater cooling circuits, HVAC systems, bilge lines, domestic freshwater systems, and compressed air service aboard commercial vessels and workboats. Note that TOHO valves do not carry DNV GL, LR, ABS, ClassNK, or BV type approval as standard — for classification society-approved applications, specify from Aik Soon's JIS-rated and class-certified ranges.
What pressure rating do TOHO bronze valves carry?
TOHO bronze valves are rated to 150 psi SWP and 300 psi W.O.G., corresponding to approximately 10 bar for steam and 20 bar for water and gas service. For higher-pressure or JIS-rated applications, Aik Soon Hardware stocks JIS 5K, 10K, 16K, and 20K rated valves from other brands.
Are TOHO valves available in Singapore?
Yes. Aik Soon Hardware stocks TOHO bronze valves in Singapore from ready stock — gate, globe, check, ball, and Y-strainer types across standard size ranges. Items can typically be collected or dispatched within one to two business days. Contact Aik Soon directly for stock confirmation and pricing.
What is the difference between a TOHO gate valve and a globe valve?
A gate valve is designed for full-open or full-closed isolation service and should not be used for throttling. A globe valve uses a disc-against-seat design that allows controlled throttling and flow regulation. In a marine utility system, gate valves are typically used for main line isolation, while globe valves are used on bypass lines, cooling water circuits, and anywhere flow rate needs to be adjusted in service.
