Product Details

1. Product Overview

The EV220B 65-100 is Danfoss Sensing Solutions' high-capacity 2/2-way servo-operated (pilot piston) solenoid valve. With a cast-iron body and flanged connections covering DN65, DN80 and DN100 (2½", 3", 4"), it is designed for large on/off flow rates of water and similar neutral media.

It is pilot-operated: when energized, the coil first lifts the pilot plunger, and the resulting pressure difference drives the main piston open — hence a minimum working differential of 0.25 bar is required. The main valve includes an integral pilot strainer to protect the pilot orifice and a water-hammer damping element to reduce closure noise at large sizes.

The standard function is normally closed (NC): de-energized the valve closes under spring/pressure, energized it opens. Seals are available in EPDM or NBR. Body and coil are ordered separately; coil voltage and enclosure rating (up to IP67) are selected to suit the application.

7. FAQ

Q1: Is the EV220B 65-100 direct-acting or pilot-operated?

A: Pilot-operated (servo piston). The coil first lifts the pilot plunger, and line pressure drives the main piston; a minimum 0.25 bar working differential is required.

Q2: What sizes and connections are available?

A: DN65, DN80 and DN100 (2½", 3", 4"), flanged, cast-iron body.

Q3: Normally open or normally closed?

A: The 65-100 high-capacity version is normally closed (NC) by standard: closed when de-energized, open when energized. Please confirm the function when ordering.

Q4: What are the Kv and flow?

A: Kv 50–130 m³/h (by DN), for large on/off flow of water and similar neutral media.

Q5: Which media and temperature?

A: Water and similar neutral liquids, medium −25 to +90°C, viscosity up to 50 cSt, ambient up to 80°C.

Q6: Is the coil ordered separately? How is voltage chosen?

A: Yes, body and coil are ordered separately. Coil voltage (e.g. 24V DC, 230V AC) and enclosure rating are selected to suit the site. Please send your conditions and coil voltage; email us to confirm the complete order code.
