วาล์วปรับสมดุลแรงดันต่าง รุ่น W-DPBV-16/25Q
รหัสสินค้าวาล์วปรับสมดุลแรงดันต่าง รุ่น W-DPBV-16/25Q
The Series W-DPBV differential pressure-balancing valve is designed to keep constant differential pressure between supply pipes and return pipes of a bypass, control valve or terminal equipment in air-conditioning or heating system. It avoids hydraulic disturbances resulting from variations in system differential pressure.
Features
• Self-acting differential pressure control, no external power needed
• The on-site setting of differential pressure
• Wide controllable range of differential pressure
• Handwheel equipped with differential pressure indicator
• Able to be shut off by handwheel
• Self-sealing measuring points to protect against leakage
• Equipped with measuring points and air vent
• Equipped with three-way measuring connector
• High-pressure guide tube with a small ball valve, eliminate general congestion
Pressure-Temperature
• Maximum Pressure: PN16, PN25
• Working Pressure: ≤400Kpa
• Temperature Range: -10°C~130°C
