Zone Valve, 15mm, 3-Way, G External, Brass, 1.6kvs
Compact design zone valve
For use with MP140 thermal actuators - low cost and silent operation
On/Off control with a soft seat for tight close off
External thread allows ease of mounting in any orientation and a simple disassembly
Brass construction, PPS cartridge and EPDM seals for excellent corrosion resistance
The VZ308E is a small linear three-way zone valve used for the control of hot or chilled water in terminal units. It is designed to be used with the MZ140 family of thermal actuators. The valves utilise a double O-ring design on the plug to ensure a leak tight seal on both valve ports, this ensures no loss of energy leakage through the valve. The valve is BSP male threaded valves with flat face seals, a range of connection sets are available to mate onto pipe. Size DN 15, G1/2A connection, 1.6 Kvs. Pressure class PN16, stroke 2.5 mm, Normally closed (A-Ab). External thread to ISO 228/1 (flat face seal).
