Static Balancing Valve – Flanged PN16
Product Details
The balancing valve is a wide range commissioning valve witch uses flanged connection technology, designed for the isolation and balancing of pipework and equipment in a HVAC and plumbing applications.
The Cast iron diaphragm valve features a flexible elastomer diaphragm that seals against the valve seat, providing a tight, leak-proof shut-off without metal-to-metal contact. Diaphragm valves are widely used in water, wastewater, chemical processing, and industrial applications where leakage resistance and corrosion performance are critical.
The Balance Regulating Valve is designed to accurately control and balance flow rates in closed-loop systems, ensuring stable hydraulic performance and optimal energy efficiency. Manufactured with a compact body and a low-resistance Y-shaped structure, the valve provides smooth flow characteristics while minimizing pressure loss across the system.
This valve is equipped with flow measuring fittings on both inlet and outlet sides, allowing precise flow measurement and convenient on-site adjustment. The fittings feature reliable self-sealing performance, enabling quick commissioning, testing, and recalibration without system shutdown or leakage risk.
Balance regulating valves are widely used in HVAC systems, water supply networks, heating and cooling circuits, and industrial piping systems, where precise flow control is essential for system efficiency, reduced operating costs, and improved overall performance.
