Description

3/4" Brass Assisted Lift Solenoid Valve – SHAKO PU220A-06

The SHAKO PU220A-06 is a high-flow 3/4" 2/2 way normally closed zero-rated assisted-lift brass solenoid valve designed for control of compressed air, water, vacuum, light oils and compatible gases and process fluids.

Combining an assisted-lift diaphragm with a large 20mm orifice, the PU220A-06 provides high flow capacity while retaining operation from zero positive pressure.

The valve can also operate under vacuum conditions, making it particularly versatile for OEM machinery, vacuum equipment, industrial automation, water systems and general fluid control applications where differential pressure cannot always be guaranteed.

Manufactured from forged brass with stainless steel internal components, the PU220A-06 is supplied with NBR seals as standard, with FKM (Viton), EPDM or HNBR alternatives available. Media temperatures from -40°C up to +180°C can be accommodated according to the selected seal material and suitable solenoid operator.

Valve Function & Operation

Function: 2/2 way normally closed

Operation: Zero-rated assisted lift

Construction: Diaphragm

Port size: 3/4" BSP

Optional thread: NPT

Orifice: 20mm

Effective area: 162mm²

The assisted-lift design combines direct mechanical lifting with diaphragm assistance, allowing the valve to operate from zero positive pressure while providing a substantially larger flow path than a conventional direct acting valve.

This makes the PU220A-06 particularly suitable for systems where little or no pressure differential is available at start-up.

The valve can also be used for suitable vacuum applications.

Pressure & Performance

AC pressure range: Vacuum to 8.5 Bar

DC pressure range: Vacuum to 5 Bar

Vacuum capability: Up to 80% vacuum

Maximum vacuum: Approximately -0.8 Bar

Not suitable between: -0.1 and +0.1 Bar

Orifice size: 20mm

Effective area: 162mm²

Flow rate: 72 L/min water @ 1 Bar ΔP

The large 20mm orifice provides high flow capacity while the assisted-lift construction allows operation from zero positive pressure.

Construction & Materials

Body: Forged brass

Internals: Stainless steel

Valve stem: Stainless steel

Construction: Assisted-lift diaphragm

Orifice: 20mm

Effective area: 162mm²

Standard seal: NBR

Optional seals:

✓ FKM (Viton)

✓ EPDM

✓ HNBR

Installation: Horizontal

Net weight: Approximately 945g

Seal & Media Selection

Correct seal selection is essential when using the PU220A-06 with different fluids and temperatures.

NBR – Standard:

✓ -15°C to +80°C

✓ Air

✓ Water

✓ Neutral gases

✓ Mineral oil

FKM (Viton):

✓ -10°C to +180°C

✓ Fuel oil

✓ Gasoline / petrol

✓ High-test gasoline

✓ Diesel fuel

HNBR:

✓ -40°C to +150°C

✓ Air

✓ Water

✓ Gear oil

✓ Engine oil

EPDM:

✓ -5°C to +130°C

✓ Hot water

✓ Detergent liquids

Always confirm chemical compatibility of the selected seal and valve materials before use with fuels, gases, oils or specialist process fluids.

Media Temperature

The maximum media temperature is determined by the selected seal material and suitable solenoid operator.

NBR: -15°C to +80°C

FKM (Viton): -10°C to +180°C

EPDM: -5°C to +130°C

HNBR: -40°C to +150°C

Overall available range: -40°C to +180°C

Flow Performance

Orifice size: 20mm

Effective area: 162mm²

Flow rate: 72 L/min water @ 1 Bar ΔP

The large diaphragm and 20mm valve orifice provide substantially increased flow capacity compared with the smaller 3/8" and 1/2" PU220A models.

Unlike a conventional pressure-assisted diaphragm valve, the assisted-lift construction allows operation from zero positive pressure, making the PU220A-06 particularly useful for tank discharge, low-pressure water systems, vacuum equipment and applications where differential pressure cannot always be guaranteed.

High Flow Zero-Rated Design

The SHAKO PU220A-06 combines the high flow capability of a diaphragm valve with assisted-lift operation from zero positive pressure.

Its large 20mm orifice and 162mm² effective area provide substantially greater flow capacity than the smaller 3/8" and 1/2" PU220A models, making the PU220A-06 particularly suitable where increased flow is required through a compact 3/4" valve.

The mechanically assisted diaphragm allows the valve to operate where conventional pilot-operated valves may fail because insufficient pressure differential is available. This makes it particularly useful for tank outlets, gravity-fed water systems, vacuum equipment, low-pressure systems and industrial applications where pressure conditions can vary during operation.

The forged brass body and stainless steel internal components provide robust industrial construction, while NBR seals are supplied as standard. Optional FKM, EPDM and HNBR seals allow the valve to be configured for different compatible media and temperatures.

When fitted with the appropriate solenoid operator, the available media temperature range extends from -40°C with HNBR seals up to +180°C with FKM seals.

An optional ATEX explosion-protected configuration is also available for hazardous-area applications, with maximum operating pressure restricted to 3 Bar and maximum media temperature restricted to +80°C.

Ordering Information

Quite surprised, cheaper than the Asco solenoid valve it replaces, looks and feels better too. Delivery from stock, Asco was 4 weeks, cheaper freight charge, half the price and works like a dream. If I ever need another solenoid valve, I'll be back to you for sure. Must say I found the service second to non as well, instant online help and guidance, clear technical data sheet, easy to order, no minimum order charges,tracked ETA delivery too..
