S22HD Series
Stainless Steel 2/2-Way Pneumatic Valve
- Direct Acting, Double Acting
- Port Size: 1/8"–2"
- Fluid Temperature: -5°C to 80°C (120℃ optional)
- Operating Pressure: 0–3.0MPa
- Media: air, water, oil, gas, steam
S22HD series is a safety-type pneumatic control valve specifically designed for hazardous environments. The stainless steel body offers multiple pressure ratings within a compact and durable structure. By adopting pneumatic control actuation, it completely eliminates the risk of electrical ignition. The pneumatic valve underwent precision machining and multi-layer sealing technology, ensuring high reliability and a long service life even under harsh conditions.
Features
- Valve body available in 304 or 316 stainless steel, providing superior resistance against acids, alkalis, and high temperatures
- Offers three pressure range options for precise system matching: 0-10 bar, 0-20 bar, and 0-30 bar
- Compact structural designs allow installation in confined spaces without compromising flow rate or response speed
- Advanced sealing system prevents fluid intrusion and supports multiple sealing materials (e.g., NBR and PTFE) for different media
- Designed with a simple and reliable structure, for easy maintenance, long lifespan, and suitable for long-term continuous operation
Applications
This pneumatic valve is engineered for explosion-proof and environmental resistance standards. It is suitable for hazardous environments containing flammable or explosive media, such as:
- Oil and gas equipment
- Chemical plants
- Mining machinery
- Fuel handling systems
- LNG stations
- Petrochemical facilities
