3-8512-T0 GF Paddle Wheel Flow Sensor Non Contact Industrial Anti Vibration

Product Specification

1.Product Overview​

The ​GF 3-8512-T0​ is a manual quarter-turn ball valve engineered for aggressive chemical and ultrapure fluid control in industrial processes. Featuring GF’s proprietary ​PVDF (polyvinylidene fluoride) body, it delivers exceptional corrosion resistance against acids, bases, and solvents while maintaining zero metallic contamination. The "T0" suffix denotes its ​glass-fiber-reinforced polyamide lever handle​ with integrated position indicator (➔ for open, ⊥ for closed). Designed for DN15 (½") pipe systems, the valve utilizes a ​PTFE-encapsulated stainless steel ball​ and EPDM seals to achieve bubble-tight shutoff (ISO 5208 Rate A leakage). Compliant with FDA, EC 1935/2004, and USP Class VI standards, it operates from -40°C to +140°C, making it ideal for pharmaceutical, semiconductor, and chemical processing applications.

​2.Key Technical Specifications​

Precision-engineered for corrosive media:

• ​Pressure Rating: 16 bar (232 psi) @ 20°C | 10 bar @ 80°C (de-rating curve provided)
• ​Temperature Range: -40°C to +140°C (EPDM seals)
• ​Connection Type: ISO 7-1 (BSPP) threaded ends
• ​Flow Coefficient (Cv)​: 5.2 (minimal pressure drop)
• ​Body Material: Homopolymer PVDF (ISO 10931 certified)
• ​Ball/Stem: 316L SS with PTFE encapsulation
• ​Seats: Reinforced PTFE
• ​Handle Torque: ≤15 Nm (ergonomic low-force operation)
• ​Fire Safety: Self-extinguishing (UL 94 V-0 rating)
• ​Standards: ISO 9001, ISO 14001, ASTM F438

3.​Primary Applications​

Corrosion-resistant fluid handling solutions:

• ​Chemical Processing: HCl, HNO₃, and NaOH dosing systems
• ​Pharmaceutical: WFI (Water for Injection) distribution (ASME BPE compliant)
• ​Semiconductor: UPW (Ultrapure Water) and CMP slurry lines
• ​Wastewater Treatment: Chlorine dioxide disinfection circuits
• ​Food & Beverage: CIP (Clean-in-Place) skids with steam sterilization
• ​Renewable Energy: Battery electrolyte handling in Li-ion production
  Suitable for vertical/horizontal installation in pumps, tanks, and filtration units. Excludes compressed air/gas service.

​4.Competitive Advantages​

Superior performance in harsh environments:

• ​Leak-Free Integrity: Double-sealed stem design prevents fugitive emissions
• ​Zero Maintenance: Self-lubricating PTFE components eliminate greasing
• ​Full-Port Geometry: 100% bore diameter ensures unrestricted flow
• ​Chemical Immunity: Resists 10,000+ chemicals (per GF Chemical Resistance Guide)
• ​Hygienic Construction: Ra ≤0.8 µm surface finish inhibits biofilm growth
• ​Lifecycle Economy: 3× longer service life vs. PP valves in oxidizing media
  Features GF’s ​TraceCore™ RFID tag​ for digital asset management and material traceability.

5.​Functional Capabilities​

Advanced operational reliability:

• ​Visual Position Confirmation: Dual-color handle indicator (green/red)
• ​Bubble-Tight Shutoff: ≤0.1 ml/min helium leakage (ISO 5208)
• ​Thermal Stability: Withstands 1,000+ steam sterilization cycles
• ​Fire-Safe Design: Metal-free construction prevents seat welding
• ​UV Resistance: Carbon-black-stabilized PVDF for outdoor use
• ​Ergonomic Operation: 150° swing arc with tactile click feedback
  Compatible with GF’s ​Quicklock​ and ​Socket Fusion​ systems for installation flexibility.
