Description

Flanged Cast Iron Normally Open Solenoid Valve PN16 RSG 860B


The RSG 860B is a heavy-duty 2/2 way normally open direct acting piston solenoid valve with a GG25 cast iron body and PN16 flanged connections.

In its normal de-energised state the valve remains open, automatically closing when electrical power is applied. This makes the 860B suitable for applications requiring unrestricted flow during normal operation or where a normally open valve function is required.

The direct acting piston construction operates without requiring a minimum pressure differential, allowing reliable operation from 0 Bar and making the valve particularly suitable for low-pressure and vacuum applications.

Available from DN15 to DN50, the 860B provides high flow capacity up to Kv 46 m³/h with working pressures according to valve size.
The robust GG25 cast iron body is supplied with PN16 flanged connections, stainless steel internals and a choice of NBR, EPDM or FKM seals to suit different media and operating temperatures.

Suitable for air, water, oils, vacuum and compatible liquids and gases.

Function & Operation

Function: 2/2 way normally open
Operation: Direct acting piston valve
Normal Position: Open when de-energised
Energised Position: Closed
Minimum Differential Pressure: 0 Bar
Port Sizes: DN15, DN20, DN25, DN32, DN40 and DN50
Flange Rating: PN16
Body Material: GG25 cast iron
Nominal Bore: DN15 to DN50

Materials

Body: GG25 cast iron
Internals: Stainless steel

Seal Options:

✓ NBR: -10°C to +90°C
✓ EPDM: -10°C to +130°C
✓ FKM: -10°C to +130°C
Ambient Temperature: Maximum +50°C
The three seal materials and their respective temperature limits are specified by RSG for the 860 family.

Pressure & Flow

Minimum Working Pressure: 0 Bar
Maximum Working Pressure according to valve size:
DN15: 0–16 Bar – Kv 5.0 m³/h
DN20: 0–12 Bar – Kv 11.0 m³/h
DN25: 0–8 Bar – Kv 13.0 m³/h
DN32: 0–16 Bar – Kv 28.0 m³/h
DN40: 0–16 Bar – Kv 30.0 m³/h
DN50: 0–15 Bar – Kv 46.0 m³/h
The direct acting design requires no minimum differential pressure and can therefore operate from 0 Bar.
Those are the manufacturer's actual GG25 pressure and Kv figures from the table on page 2.

Coil & Electrical

DN15 to DN25:
Coil: 30 Watt, 60mm diameter

DN32 to DN50:
