A pneumatic 3 way valve has three ports — typically Pressure (P), Outlet (A), and Exhaust (B) — and can switch flow between two different paths, or mix/divert flow. Unlike a 2-way valve (on/off), a 3-way valve allows you to direct flow to one of two outlets, or alternate between two sources. Common configurations include normally closed (NC), normally open (NO), and universal (directional control). This makes it ideal for applications like alternating filter systems, cylinder control, and media blending.

For standard models (TV-3W-P series), our lead time is 4-6 weeks from order confirmation. For high-performance or custom designs (TV-3W-HP), typical lead time is 6-8 weeks. We offer DDP (Delivered Duty Paid) shipping for USA customers, which means you receive a all-inclusive price with no surprise customs fees. A typical order of 10 units (1" NPT) ships via air freight at $480-$680 (3-4 days) or sea freight at $220-$380 (25-30 days). Request a real-time quote to get exact numbers for your port.

Double-acting actuators use air pressure for both opening and closing — they are more compact, lighter, and lower cost. They are ideal for applications where compressed air is always available and fail-safe is not required. Spring-return actuators use a spring to return the valve to a safe position (fail-open or fail-closed) upon loss of air pressure or power. They are essential for safety-critical systems (chemical reactors, emergency shutdown, boiler control). For general remote on/off control with no safety requirement, double-acting is often sufficient. For fail-safe operation (required in SIL-rated loops), spring-return is the standard. Our technical team can help you make the right choice — contact us for a sizing consultation.

All Thriveon pneumatic 3 way valves come with a standard 24-month warranty (36 months for our HP series). Coverage includes manufacturing defects, material failure, and actuator seal leakage. We provide lifetime technical support via email (info@thriveonvalve.com), phone (+86-311-86935302), and WhatsApp. For critical applications, we can arrange on-site commissioning support (remote or in-person) at cost. We also maintain a spare parts inventory for quick replacement of seals, O-rings, and actuator components. Free replacement parts are shipped within 48 hours for any warranty claim.

We accept TT (Telegraph Transfer), Wire Transfer, Letter of Credit (L/C) at sight, PayPal (for smaller amounts), and Alibaba Trade Assurance. For first-time orders, typical terms are 30% deposit / 70% balance before shipment. For repeat customers and established relationships, we can offer more flexible terms (e.g., 30% / 70% after inspection). All payments are processed through our corporate account with full invoice and customs documentation provided. Contact our finance team for a detailed quote with your preferred payment method.

Yes — we offer free samples for qualified buyers (engineering firms, OEMs, and distributors with a verifiable company profile). You pay only the shipping cost. Standard sample is one unit of our TV-3W-P series in 1/2" NPT with double-acting actuator. We also offer loaner units for evaluation at your facility. Apply for a free sample here — we typically respond within 12 business hours.

Every pneumatic 3 way valve undergoes a multi-stage QC process: ① Incoming material inspection (PMI test on all alloys). ② Dimensional check per ASME B16.34 & ISO 17292. ③ Hydrostatic shell test at 1.5x rated pressure. ④ Pneumatic seat leakage test (ISO 5208 Rate A or B). ⑤ Actuator stroke test (full open/close cycle, 10 repetitions). ⑥ Final visual and documentation check. We also offer optional third-party inspection (SGS, BV, Intertek) at your cost. A certified test report is included with every shipment.
