■ Introduction

NSV1.6VW Direct-Acting Solenoid Valve provides the solution of the problem on valve body too big and valve opening time too long in refrigeration system. Its advantages: 1, Valve opening time short; 2, Small size of valve body; 3, Cost saving. After solenoid coil opens, It controls by the changing-over of solenoid valve port from suction. the solenoid valve has low working noise, easier installation, it can be widely used in household freezer and small refrigeration equipment.

NSV1.6VW Direct-Acting Solenoid Valve with tetrafluoro core iron sealing inside which can be easily disassembled and maintained, the leakage effect better than other same type products.

Direct-Acting Solenoid Valve: Valve open when power on and valve close when power off

Differential pressure of Action: 0 ～ 2.06MPa

Weight: 0.18KG

Max. Working pressure: 2.94MPa

Connection position: Side connection for Inlet

■ Introduction

NSV2.2A direct-acting solenoid valves feature compact structure, rational design, easy installation and maintenance, and act rapidly.

These series can be widely used in refrigeration, pneumatic and hydraulic systems. Solenoid valves use full-closed magnetic coil and DIN international standard electric plug, so it is characterized by its good insulation, waterproof, moisture proof, anti-vibration and corrosion resistance.

■ Operating principle

The pull of the solenoid coil opens the valve port directly by lifting the seat disc off the valve seat. While de-energized in the coil, plug stem will drop and close the valve port because of spring force and its weight.

■ Type ＆ data

The Kv value is the water flow in m3/h at a pressure drop across valve of 0.1MPa, ρ=1000 kg/m3

Letter after the model: “W” means solder ODF, “A”&”B” means different valve bodies, “K” means normal opened valves.
