真鍮製自動フロートバルブ BSP ネジ DN15-DN50 | 水槽レベル調整弁

製品概要

This Brass Hydraulic Float Valve is a direct-acting float-controlled shut-off valve designed for automatic liquid level regulation in small to medium tanks, cooling towers, and industrial equipment. The float mechanism directly drives the valve stem and disc to open or close the flow passage based on water level changes. With a brass body and cover, PTFE seats, and NBR/EPDM seals, this valve offers excellent corrosion resistance and stable sealing performance. It supports standard threaded connections (ISO228) and is suitable for water, 空気, and light oil applications. Its compact design, high reliability, and easy installation make it an ideal choice for precise level control in space-constrained systems.

技術仕様

主な特長

• Direct Float Actuation: The float is directly linked to the valve stem, delivering instant response to water level changes with no external pilot or power required.
• Durable Brass Construction: The valve body, cover, stem, and ball are all made of high-quality brass, offering excellent corrosion resistance, machinability, and long service life in both water and light oil systems.
• PTFE Sealing System: PTFE seats provide low friction, excellent chemical inertness, and reliable shut-off over a wide temperature range (-20°C to 150°C).
• Versatile Media Compatibility: Suitable for water, 空気, and oil, making it adaptable to various industrial fluid control scenarios.
• Wide Size Range: Available from DN15 (1/2″) to DN50 (2″) to meet different flow requirements for small to medium tanks.
• Standard Threaded Connection: ISO228 standard threads ensure compatibility with global piping systems, simplifying installation and maintenance.
• Full Customization Support: Offers OEM, ODM, and OBM services including logo printing, 梱包, and design modifications (minimum order quantities apply).

よくある質問

Q1: Can this float valve be used in hot water systems?
A1: はい. The working temperature range is -20°C to 150°C, making it suitable for hot water applications (例えば, heating system make-up and domestic hot water tanks). PTFE seals perform stably at high temperatures, provided the medium temperature does not exceed 150°C.

第2四半期: What tank flow capacities are suitable for DN15 vs DN50?
A2: Selection depends on the inlet pipe size, required fill flow rate, and working pressure. General recommendation: DN15 suits small make-up tanks (例えば, domestic storage), while DN50 suits medium-flow industrial tanks or cooling towers. Provide your operating parameters, and our technical team will assist with precise sizing.

Q3: Can this valve handle oil media? Are there viscosity limitations?
A3: It is suitable for light oils (例えば, hydraulic oil, lubricating oil, ディーゼル). Recommended kinematic viscosity ≤46 cSt at 40°C. High-viscosity oils or media with solid particles may affect float response and seal life. Please consult us for customized solutions.

Q4: What thread standard is used? Can it be adapted to NPT or BSP?
A4: Standard products use ISO228 thread (equivalent to BSP). If NPT or BSPT is required, we support customization based on samples or drawings. Please contact us for minimum order quantities.

Q5: Is the float rod length adjustable to suit different tank depths?
A5: The float rod is of standard fixed length, but different level settings can be achieved by bending the rod or adjusting the mounting position. For custom lengths or special float materials, please contact us for ODM customization.
