Hongsen Hvp28 Piston Globe Valve Solenoid Valve

Product Description

Product Description:

·Model HVH piston type solenoid valve is a twice open-type solenoid valve to be suitable to one-way flow.
·Model HVH piston type solenoid valve is used on the liquid, air suction and hot vapor pipes of the refrigeration, cold storage and air conditioning facilities.
·The coil of varies voltages is available for Model HVH piston type solenoid valve with a universal valve body.
·Model HVH piston type solenoid valve could be supplied in whole or in split, that means valve body and coil could be supplied separately.
Product Model:

Model	Size	△P(bar)		Max Operating Pressure(bar)	Kv(/h)
Model	Weld Connection	Min.	MOPD LiquidMOP	Max Operating Pressure(bar)	Kv(/h)
HVD25	1-1/8ODF	0.2	31	45	10
HVD32	1-3/8ODF	0.2	31	45	16
HVD40	1-5/8ODF	0.2	31	45	25

1) Kv value: The flow rate (m³/h) of water of density 1t/m³ passing through the solenoid valve with the pressure differential of 100 KPa.
2) The MOPD of gaseous medium is about 1 bar higher than that of liquid.
