A pneumatic spare coil is an essential replacement component used in solenoid-operated pneumatic valves. It generates the electromagnetic field required to actuate the valve’s plunger, enabling reliable control of air flow in automation and fluid-control systems. Designed for durability and easy installation, the spare coil restores optimal performance to pneumatic solenoid valves without requiring full valve replacement.
Available in multiple sizes and voltage ratings (12V DC, 24V DC, 110V AC, 220V AC) to fit various valve brands and models.
The SVZ-2.5 is a compact, economical 2-way solenoid valve designed primarily for use in welding machines, pneumatic control circuits or gas distribution systems. The “2/2” configuration means it has two ports and two switching positions (open/closed). With an approximate 2.5 mm orifice, it allows moderate flow rates suitable for control of air, inert/gas flows (e.g., argon/CO₂) or light fluids depending on variant. In its de-energised state (for the “normally closed” version) the valve blocks flow; when energised, it opens (some may be N.O. or N.C. depending model—check your supplier).
Valve type: 2/2 way
Port size/thread: ~ 1/8″ (G1/8) or hose ~8 mm
Orifice: ~2.5 mm
Max pressure: ~10 bar (in air applications)
Temperature: ~5 °C to 50 °C (depending variant/seal)
Coil voltages: Variants eg. 24 V DC, 220 V AC
Body material: Brass (in many gas/welding variants)
Medium: Filtered air, inert gas, light fluids (check compatibility)
The TP22-08 is a compact, economical 2-port, 2-way solenoid valve from the Techno TP Series. It features a quarter-inch (¼″) port size, designed for use with filtered, lubricated compressed air, with a working pressure up to about 10 bar and ambient/medium temperatures of approx 5 °C to 50 °C. The valve supports various coil voltage options making it flexible for different supply systems. In its de-energised state (dependent on variant) it remains in one position (usually closed in standard economy models), and when the coil is energised it switches state, enabling control of pneumatic flow in automation or industrial air circuits.
Port size: ¼″ (1/4″)
Way: 2/2 (two-way)
Pressure: Up to ~10 kgf/cm² (≈10 bar)
Temperature: ~5-50 °C
Medium: Filtered, lubricated compressed air (~40 µm)
Coil voltage: Options (12 VDC, 24 VDC, 24 VAC, 220 VAC) – confirm variant
Thread size: ¼″ (6.35 mm) or as per listing
Series: TP Series (Techno)
The 2S-025-08 is a compact, economical 2-way, 2-position solenoid valve in the 2S Series designed for general pneumatic or low-pressure fluid systems. In its standard configuration it is normally closed (i.e., in the de-energised state the valve remains shut, and when the coil is powered the valve opens). The valve features a ~¼″ (DN08) port size, small orifice (~2.5 mm) and is suitable for use with filtered air, water or non-corrosive fluids up to about 10 bar, with ambient and media temperature around -5 °C to +80 °C in many variants. Its construction allows for quick switching and compact installation in automation, pneumatic control or fluid circuits.
Port size: ¼″ (DN08)
Orifice: ~2.5 mm
Pressure range: Up to ~1.0 MPa (10 bar)
Temperature range: approx -5 °C to +80 °C (depending on seal material)
Body material: Stainless steel variant (some listings), possibly brass in other variants
Function: Normally Closed (default) for many versions; check if normally open variant exists
Coil voltage: Various options (12 V DC, 24 V DC, 220 V AC) depending variant
Medium: Filtered air (e.g., 40 micron), also water, light oil, gas
The Techno 2W-160-15 (part no. 955305) is a direct-acting 2-port, 2-way solenoid valve configured to operate in a normally open (N.O.) fail-safe state. In its de-energised state, the valve remains open, allowing fluid or gas flow; when the solenoid coil is energized, the valve closes, stopping the flow. This design is ideal for applications where continuous flow is required unless a signal is applied to shut off the flow.
Port size: ½″ (G1/2) female threads
Orifice: ~16 mm
Pressure range: up to ~1 MPa (10 bar) under N.O. condition
Temperature range: –5 °C to +80 °C (standard NBR seal), extended with EPDM/Viton
Media compatibility: air, water, neutral liquids (check seal compatibility for oil/gas)
Coil Voltages: 12 VDC / 24 VDC / 24 VAC / 110 VAC / 220 VAC (variant dependent)
Body Material: Brass
Seal Material: NBR (standard) / EPDM / Viton (optional)
The 2W-160-15 N/O Solenoid Valve is a 2/2-way (two-way, two-position) normally open solenoid valve designed for the automatic control of air, water, gas, and light oil. When the solenoid coil is de-energized, the valve remains open to allow flow; when energized, the valve closes to stop the flow.
Constructed with a durable brass body and a high-quality diaphragm, this valve provides reliable sealing, corrosion resistance, and long service life. It is widely used in water treatment systems, pneumatic automation, and fluid control applications.
