Description
Overview
The Parker-Sporlan 475435 is a heavy-duty Two-Way Pressure Independent Control Valve (PICV) engineered for precise hydronic flow management in commercial HVAC systems. Combining a brass body with stainless steel trim, this assembly delivers equal percentage flow characteristics and eliminates the need for separate balancing valves — simplifying installation while maximizing system efficiency.
Key Features
- Two-way, normally closed (NC) valve configuration
- Equal percentage flow characteristic for accurate modulating control
- Pressure independent design maintains set flow regardless of system pressure fluctuations
- Brass valve body with stainless steel trim for corrosion resistance and long service life
- 2-1/2″ NPT end connections for straightforward pipe installation
- Maximum flow rate: 95 GPM
- Spring return mechanism ensures fail-safe normally closed position on power loss
- Two-position SPST direct coupled actuator for reliable on/off control
