PRESSURE INDEPENDENT CONTROL VALVES AND ACTUATORS One device with three integrated functions Control valve with integrated adjustable flow limiter and automatic pressure regulator simplifies installation and commissioning. usa.
Achieve your design intent with Siemens PICV Enjoy the freedom to choose a better solution of 2-way Pressure Independent Control Valves (PICVs) with a comprehensive portfolio from 1/2 to 6 inches. Pressure independent control valves (PICVs) improve temperatures at the right level. HVAC equipment system performance and optimize delta-T. Siemens such as pumps, can work easier, generating greater PICVs integrate three functions into a single device.
Advantages of our PICVs: 1. Valve Actuator – Spring return and non-spring return actuators to meet most control requirements 1 – Visual position indication – Manual override 2. Field Adjustable Flow Limiter – Full stroke always maintained with independent flow limiter enabling higher control accuracy – Easily adjust maximum flow at any time when usage patterns change – Presetting prevents oversupply to the coil 2 3.
How PICVs work: Hot/chilled water or 50% water-glycol solutions in closed loop systems enter the valve and pass through a variable rectangular adjustable flow limiter (C) that is connected to the ring with the dial (A) for presetting the maximum volumetric flow. The medium then flows through the temperature control valve A (D) with a linear characteristic and a stroke of 5 or 6.5 mm. A powerful spring (B) ensures safe closing.
