Pneumatic three-way ball valve

氣動(dòng)三通球閥

Detailed analysis of pneumatic three-way ball valve:
1. Types and structures of pneumatic three-way ball valves
L-type and T-shaped:
L-type: used for medium flow direction switching (such as vertical channel connection), suitable for diversion scenarios.
T-type: Achieving three channel interconnection (diversion or merging), commonly used in multi pipeline control.
Valve seat design:
Two seat structure (basic version) or four seat structure (high sealing performance).
2. Technical parameters and performance characteristics
Path and pressure:
Diameter range: DN15-DN250 (common industrial models).
Nominal pressure: 1.6-6.4MPa (depending on the material).
Driving mode:
Double acting (requires continuous air supply) or single acting (spring reset, maintains state in case of malfunction).
Applicable medium:
For gases, liquids, vapors, oils, etc., corrosion resistant materials such as PTFE/PPL lining can be selected.
3. E-commerce models and price references for sale
Low price version:
304 stainless steel T-shaped (240 yuan).
Mid to high end models:
316 stainless steel sanitary grade (392 yuan).
CPVC plastic L-type (915 yuan).
4. Manufacturer and brand recommendations
Domestic mainstream brands:
One standard (sanitary grade stainless steel), Woying (UPVC plastic valve).
International brands:
Rotork (Profibus protocol compatible, customized).
5. Selection suggestions
Chemical/Water Treatment: Prioritize UPVC/CPVC materials (acid and alkali resistant).
Food/medicine: 316 stainless steel sanitary grade (clamp quick installation type) is required.
If further comparison of specific model parameters (such as sealing grade or response speed) is needed, the direction of demand can be supplemented.
