Advance Flanged Manual Balancing Valve – Double Regulating Valve PN16/PN20
Advance Flanged Balancing Valve DN80-DN300, PN16/PN20 rating. Double regulation with tamperproof setting for HVAC & process plants. Available at PC
Overview
The Advance Flanged Manual Balancing Valve is a double regulating valve designed for precise flow control and system balancing in hydronic and process applications. Built to BS 7350 standards, this valve enables plant engineers to commission and optimize piping systems by accurately measuring and regulating flow rates across circuits.
The valve features a non-rising stainless steel spindle with a tamperproof locking mechanism, allowing operators to set a maximum regulated position while retaining full shut-off capability. EPDM sealing ensures positive shut-off, and integrated pressure test cocks enable differential pressure measurement using portable instruments for flow calculation.
Available in sizes DN80 to DN300 with PN16 and PN20 pressure ratings, this balancing valve is suitable for chilled water systems, hot water circuits, and process plants requiring flow measurement and double regulation functions.
Key Features
- Precise double regulation with concealed limited stroke mechanism
- Tamperproof setting with lockshield and lock screw arrangement
- EPDM sealing disc for positive shut-off (Teflon optional)
- Integrated pressure test cocks for differential pressure measurement
- Indicator scale showing handle turns from fully shut to fully open
- Micrometer scale allows fine setting up to 1/10 of a handwheel turn
- Epoxy-coated internals for corrosion resistance
- Flow direction marked on valve body
