2/2 Way Proportional NC Valve - VP 204-505 V 15 SAL 80 12/00

Staiger GmbH & Co. KG

2/2-way proportional NC design (Ø 15 mm cartridge).
Current-controlled for precise flow regulation.
Service life 150 million switching cycles.
Lightweight (23 g), compact geometry, any mounting position.
Media air, oxygen, and inert gases.
IP60/IP65 protection depending on plug.

The 2/2 way proportional NC valve is a compact, lightweight valve with an outside diameter of 15 mm, designed for precise control and current-controlled operation. It is suitable for use with air, oxygen, and inert gases, and offers high durability with a service life of 150 million switching cycles. The valve is IP60 protected in its standard form and can achieve up to IP65 protection with suitable plugs. It operates within a pressure range of 0–3 bar(g) and has a flow rate of up to 52 ± 4 l/min at 3 bar(g) and 20°C. The valve is made from materials like 1.4305, 1.4105, 1.4310, FKM, and PTFE, and is suitable for various media after testing. It is also designed for low weight and compact geometry, with a weight of 23 g and a compact design that allows for any mounting position. The valve is precisely controllable and offers a wide range of technical specifications, including a flow coefficient up to 0.98 l/min, a temperature range of -40 to 80°C, and a service life of 150 million cycles. The valve is suitable for use in various applications, including industrial and automation systems, and is designed for reliable and efficient operation.
