Purpose
Proportion Integral Regulating Valve ZLVG-7000 series thread copper valve could be matched with ZLVA-7150 or ZLVA-3000 actuator, could regulate cool or heat water flow, is widely applied to control liquid for central air-condition, heating and water treatment system |
Material and technical data：
◆ Sealer of valve stem: Y gasket ring and O type combination, NBR rubber seal component, PTFE seal cover
◆ Valve stem: Stainless steel AISI304
◆ Valve plug: brass
◆ Other components are all in brass.
◆ Pressure-bearing:1.6MPa; service medium: water; liquid temperature: 1~95℃
◆ Connection manner: BSP parallel inner screw (BS21); flow characteristics: equal percentage ◆ Leakage amount：less than KV value 0.05% |
Installation and maintenance：
◆ Valve stem goes down to cut off the valve.
◆ Keep the pipe clean before installing valve, without oxide skin and metal sheet or other sundries.
◆ Make sure homocentric by connecting pipe and valve body, unaffected by vibration, flow direction shall be same as indication in the valve body.
◆ The actuator shall be install above valve body vertically, leave sufficient space for daily maintenance (such as disassemble actuator)
◆ Cut off or insulate power when make maintenance to valve, without pressure for water system. |
