Description

Flanged Stainless Steel NO Solenoid Valve PN40 RSG 860B

The RSG 860B is a heavy-duty 2/2 way normally open direct acting piston solenoid valve with a 1.4305 stainless steel body and PN40 flanged connections.

In its normal de-energised state the valve remains open, automatically closing when electrical power is applied. This makes the 860B particularly 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 suitable for low-pressure and vacuum applications.

Available from DN15 to DN50, the 860B combines high flow capacity up to Kv 46 m³/h with working pressures up to 25 Bar depending upon valve size.

The stainless steel construction provides improved corrosion resistance for demanding industrial process applications, with stainless steel internals and a choice of EPDM or FKM seals according to the process media and operating temperature.

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: PN40

Body Material: 1.4305 stainless steel

Nominal Bore: DN15 to DN50

Materials

Body: 1.4305 stainless steel

Internals: Stainless steel

Seal Options:

✓ EPDM: -10°C to +130°C

✓ FKM: -10°C to +130°C

Ambient Temperature: Maximum +50°C

The general 860 specification lists NBR, EPDM and FKM, all with their respective temperature limits. However, RSG's specific stainless-steel ordering tables list the stainless variants with EPDM or FKM, so I'd use those two for this body-specific ecommerce product.

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: 0–25 Bar – Kv 28.0 m³/h

DN40: 0–20 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.

These pressure and Kv figures are the manufacturer's specific values for the 1.4305 stainless version.

Coil & Electrical

DN15 to DN25:

Coil: 30 Watt, 60mm diameter

DN32 to DN50:

Coil: 60 Watt, 70mm diameter
