YOSHITAKE GD-27BP Pressure Reducing Valve – Water
Made in Japan
Manufacturer: Yoshitake
Model: GD-27BP
1. Combination of pressure reducing function, by-pass function and stop function that provide saving cost and space.
2. Enable for a wide range of pressure control in a water supply system.
3. Wetted parts are made of corrosion-resistant material to prevent rusty water.
4. Pressure balance structure can keep the reduced pressure at a constant level without being effected by inlet pressure.
5. Maintenance and inspection can be conducted easily by disassembling the upper side only.
