Name: Festo 535987 Air solenoid valve NVF3-MOH-5/2-K-1/4-EX
Brand: Festo

Air solenoid valve NVF3-MOH-5/2-K-1/4-EX

The Festo part number 535987 is a 53 mm wide industrial component featuring a 5/2- or 3/2-way monostable valve function with electrical actuation and a plate seat structural design. It delivers a normal nominal flow rate of 900 l/min through a sub-base pneumatic working port at an operating pressure range of 0.2 MPa to 1 MPa (2 bar to 10 bar), utilizing a mechanical spring reset method and soft sealing principle with an adjustable exhaust air function. This unit includes ATEX category II 2G and II 2D certifications, UKCA marking according to UK EX instructions, and explosion protection ratings for gas (Ex h IIC T6 Gb) and dust (Ex h IIIC T70°C Db) within an explosive ambient temperature range of -5°C to +40°C, operating via a solenoid coil ordered separately.

Why no listed price?

Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading.

Engineering context

Identification and RFQ Guidance

Confirm the exact configuration

Use the manufacturer part number and model code—not appearance alone. Connection, size, material, voltage, pressure, seal, and control options can differ within the same product family.

What to include in your RFQ

Provide quantity, delivery country and ZIP/postal code, required condition, target date, and photographs of the existing nameplate when available.
