Stainless Steel 3PC Manual Tank Bottom Valve with lock
Product Description
Structure & Design Features
- Three-piece structure (3PC): Comprising a valve body, bonnet, and connecting flange for easy installation and maintenance. For example, the arc-shaped flange can be pre-welded to the tank bottom before valve assembly to avoid heat damage and minimize residual dead legs (as noted in reference materials).
- Tilted stem design: Angled at ~105° to optimize space utilization at tank bottoms while preventing material accumulation and ensuring smooth fluid discharge.
- Mirror polishing: Internal surfaces polished to a roughness of 0.2-0.45μm (some models achieve 0.25μm), meeting hygienic standards and reducing media residue.
- Self-cleaning capability: 35° installation angle combined with an arc-shaped connection promotes self-draining to minimize residue.
2. Materials & Sealing
- Body material: SUS304/SUS316L stainless steel for corrosion resistance in sterile environments (food/pharmaceutical industries).
- Sealing materials: Options include PTFE, EPDM, and FPM, with FDA-compliant variants available for high-temperature or corrosive media.
- Safety enhancements: Fire-safe designs (metal-to-metal sealing during fires) and anti-static devices (spring-loaded ball bearings to discharge static) on select models.
3. Technical Specifications
- Port sizes: DN10-DN100 (1/2"-4"), with DN20-DN80 (3/4"-3") options for specific models.
- Pressure rating: ≤10 bar (145 psi); some variants withstand up to 6.4 MPa.
- Temperature range:
- EPDM seals: -20~135°C
- FPM seals: -30~230°C
- Connections: Tri-clamp, welded, sanitary flange, threaded, or quick-disconnect, compatible with DIN/SMS standards.
4. Applications
- Industries: Pharmaceuticals, dairy, beverages, and bioengineering, ideal for fermentation tanks, mixing vessels, and CIP/SIP-compatible equipment requiring zero-residue discharge.
- Functionality: Enables dead-leg-free drainage, supports full material mixing in agitated tanks, and simplifies cleaning.
5. Additional Advantages
- Easy maintenance: Adjustable upper seal design allows leak repair without full disassembly.
- Upgradability: Manual operation with optional pneumatic actuators for automated control.
- Certifications: ISO 5211-compliant mounting pads for direct actuator installation, reducing accessory costs.
