Control valves RV 10x

Description
Control valves series RV 102 are two-way or three-way valves with internal threaded connection. Valve body is made of bronze.
Control valves series RV 103 are two-way or three-way valves with flanged connection. Valve body is made of grey cast iron. Valves are optionally manufactured in the following executions:

Valves RV 102 and RV 103 are equipped with hand wheel or they are especially designed for actuators of the following producers: Siemens (Landis & Staefa), Johnson Controls, Honeywell, Belimo, Ekorex+ and ZPA Nová Paka.

Application
Valves are designed for application in heating, ventilation or air conditioning systems for maximal temperature 150^oC.

Process media
Valve series RV 102 and RV 103 are designed to regulate the flow and pressure of liquids, gases and vapours without abrasive particles e.g. water, low-pressure steam, (it applies to RV 102 only), air and other media compatible with material of the valve inner parts. Medium acidity and alkalinity should not exceed range of pH 4.5 to 9.5. To ensure reliable regulation, producer recommends to pipe a strainer in front of the valve into pipeline.
