Stainless Steel 3PC Manual Tank Bottom Valve with lock
Product Description
Structure & Design Features
- Three-piece structure (3PC): Ingeniously designed with a valve body, bonnet, and connecting flange, ensuring effortless installation and maintenance. The arc-shaped flange can be seamlessly pre-welded to the tank bottom prior to valve assembly, thereby preventing heat damage and significantly reducing residual dead legs, as highlighted in our reference materials.
- Tilted stem design: Elegantly angled at approximately 105°, this design optimizes space utilization at tank bottoms, effectively preventing material accumulation and ensuring smooth and efficient fluid discharge.
- Mirror polishing: Experience unrivaled hygiene with internal surfaces polished to a precision roughness of 0.2-0.45μm, with certain models achieving an impressive 0.25μm, meeting stringent hygienic standards and minimizing media residue.
- Self-cleaning capability: The 35° installation angle, combined with an artfully crafted arc-shaped connection, enhances self-draining and minimizes residue, delivering exceptional cleanliness.
2. Materials & Sealing
- Body material: Crafted from SUS304/SUS316L stainless steel, offering superior corrosion resistance, especially vital for sterile environments within the food and pharmaceutical industries.
- Sealing materials: Versatile options including PTFE, EPDM, and FPM, with available FDA-compliant variants designed to withstand high temperatures or corrosive media, ensuring safety and reliability.
- Safety enhancements: Features include cutting-edge fire-safe designs with metal-to-metal sealing during fires and anti-static devices utilizing spring-loaded ball bearings to effectively discharge static in select models.
3. Technical Specifications
- Port sizes: Available in DN10-DN100 (1/2"-4"), with specialized options ranging DN20-DN80 (3/4"-3") to cater to specific model requirements.
- Pressure rating: Robustly engineered to withstand pressures ≤10 bar (145 psi), with some variants capable of enduring up to 6.4 MPa.
- Temperature range:
- EPDM seals: Remarkably resilient from -20~135°C.
- FPM seals: Withstands an impressive range from -30~230°C.
- Connections: Versatile connectivity options include Tri-clamp, welded, sanitary flange, threaded, or quick-disconnect, all compliant with DIN/SMS standards for seamless integration.
4. Applications
- Industries: Perfectly suited for pharmaceuticals, dairy, beverages, and bioengineering. Ideal for fermentation tanks, mixing vessels, and CIP/SIP-compatible equipment needing zero-residue discharge.
- Functionality: Facilitates dead-leg-free drainage, supports thorough material mixing in agitated tanks, and significantly simplifies cleaning procedures.
5. Additional Advantages
- Easy maintenance: Enjoy hassle-free maintenance with an adjustable upper seal design that allows for leak repair without needing full disassembly.
- Upgradability: Offers manual operation with the option for pneumatic actuators enabling smooth transition to automated control.
- Certifications: ISO 5211-compliant mounting pads ensure direct actuator installation, providing cost-efficient accessory solutions.
