Brand Name: Sinro
Model Number: SR13 series
Place of Origin: Guangzhou,China
DESCRIPTION
SR13 series Type B floating/modulating valve, which is constituted with SRA13 series actuator and SRV13 series valve body, are mainly used in central air-conditioning cool/heat water system. It can accurately control the flow of chilled/hot medium according to the actual requirement, and won’t result in a sudden change of temperature.
SRA13 series actuator has 3 models: standard 3-point type, overtime protection 3-point type and internal PCB type. With built-in self testing function, it can remain the data about actuator pitch stroke and valve stem stroke. It can switch working status quickly, too. The model with PCB can receive 0~10V (input impedance: 200KΩ) or 4~20mA DC (input impedance: 500Ω) input control signal, and provide proportional control, and 0~10Vdc (1mA) feed back signal. The SRV13 valve has two types: 2-way and 3-way. And it has four sizes: 1/2”, 3/4”, 1” and 11/4”. There are 11 kinds of specifications classified by the access type and the fluid characteristic. There are also different pipe connection for customers’ selection: BSP(G), NPSC(N), SWEAT(S), INVERTED FLARE(F), etc.
SR13 series Type B valve has the advantages of large flow rate, high differential pressure, low noise, stable and dependable performances. It can withstand the high/low temperature and high humidity condition often appeared in concealed fan coil unit.
