   ZTV/ZTR The control valves in the ZTV/ZTR series are available in 2- and 3-way versions. Body in brass, spindle in stainless steel. Plug in brass and O-ring in EPDM.The valves have equal percentage flow characteristics. Function The 2-way valve is closed when the spindle is placed in the highest position and completely open in the lowest position. The 3-way valve is closed between port A and AB (the ports placed opposite of each other) when the spindle is in the highest position. While in this position, the valve is open between the lowest port B and the joint outgoing port AB. When the spindle is in its lowest position, the 3-way valve is completely open between port A and AB and thereby closed between the lowest port B and the joint port AB. 2-way valve ABAB 3-way valve ZTV/ZTR Zone valves, 2-way and 3-way DN15...DN25 ã For water and refrigerants (max. 30 % glycol)ã Media temperature 1...110°Cã Pressure class PN16The valves in the ZTV/ZTR series are used for control of hot and cold water in climate, heating and ventilation systems.ã Rangeability better than 50:1ã Differential pressure up to 350 kPaã No leakage when the valve is closed. Sizes The valves are available with Kvs values from 0.25 (DN15) to 7.0 (DN25). Installation The valve should be mounted with the spindle in a vertical position or 90° to the right or left. It must not be mounted with the spindle downwards.At high media temperature, the valve should be mounted with the spindle at the side to reduce heating of the valve actuator.To make sure that the plug is leak proofed, mount the 2-way valve so that the arrow on the body is directed downstream.The 3-way valve is of mixing type and should therefore be mounted in the mixing point, according to the flow direction marks on the valve. Typical applications The valves are used for control of hot and cold water in heating, ventilation and indoor climate systems. They can also control refrigerants in for example liquid connected recovery systems. Valve actuators The valves are intended to be used together with actuator RVAZ4-24A (0...10 V) or RVAZ4-24 (3-point).  revision  12 2011  2  ZTV/ZTR Models 2-way valves Connection Kvs Max. diff. pressureZTV15-0,25 DN150.25350 kPa ZTV15-0,4 DN150.4350 kPa ZTV15-0,6 DN150.6350 kPa ZTV15-1,0 DN151.0350 kPa ZTV15-1,6 DN151.6350 kPa ZTV20-2,0 DN202.0250 kPa ZTV20-2,5 DN202.5250 kPa ZTV20-4,0 DN204.0150 kPa ZTV20-6,0 DN206.0150 kPa ZTV25-7,0 DN257.070 kPa  Technical data Pressure class PN16 (1.6 MPa) Connection External thread, see table below Flow characteristics Equal percentageRangeability 50:1Stroke 5.5 mm Leakage 0% in closed positionMedia Hot or cold water.
