Introducing the Stainless Steel 3PC Manual Tank Bottom Valve, equipped with a secure locking mechanism, a marvel of engineering excellence.
Product Description
Structure & Design Features
- Three-piece structure (3PC): This innovative design includes a valve body, bonnet, and connecting flange, ensuring effortless installation and maintenance. Notably, the arc-shaped flange can be pre-welded to the tank bottom, safeguarding against heat damage while significantly reducing residual dead legs, as highlighted in technical references.
- Tilted stem design: Ingeniously angled at approximately 105°, this design optimizes spatial utilization at tank bottoms, preventing material build-up and ensuring a seamless fluid discharge process.
- Mirror polishing: The internal surfaces boast a gleaming polish with a roughness of 0.2-0.45μm, with select models achieving 0.25μm. This meets the highest hygienic standards, effectively reducing media residue.
- Self-cleaning capability: A strategic 35° installation angle complements the arc-shaped connection, fostering self-drainage to minimize residue accumulation, enhancing operational efficiency.
2. Materials & Sealing
- Body material: Constructed from SUS304/SUS316L stainless steel, this valve offers superior corrosion resistance, ideal for sterile environments such as the food and pharmaceutical industries.
- Sealing materials: Choose from PTFE, EPDM, and FPM options, with FDA-compliant variants available to withstand high temperatures or corrosive media, ensuring versatility and safety.
- Safety enhancements: Incorporating fire-safe designs with robust metal-to-metal sealing during fires, and anti-static devices with spring-loaded ball bearings to safely discharge static on select models.
3. Technical Specifications
- Port sizes: Offering a versatile range from DN10-DN100 (1/2"-4"), including DN20-DN80 (3/4"-3") options tailored for specific models.
- Pressure rating: Designed to handle pressure up to 10 bar (145 psi), with select variants enduring up to 6.4 MPa, ensuring reliability under demanding conditions.
- Temperature range:
- EPDM seals: Resiliently functioning from -20~135°C, accommodating diverse operational needs.
- FPM seals: Withstanding temperatures from -30~230°C, providing robust performance in extreme conditions.
- Connections: Compatible with DIN/SMS standards, available in tri-clamp, welded, sanitary flange, threaded, or quick-disconnect options for seamless integration.
4. Applications
- Industries: Perfectly suited for pharmaceuticals, dairy, beverages, and bioengineering sectors, this valve is ideal for fermentation tanks, mixing vessels, and CIP/SIP-compatible equipment requiring impeccable zero-residue discharge.
- Functionality: Expertly enables dead-leg-free drainage, supports comprehensive material mixing in agitated tanks, and simplifies the cleaning process.
5. Additional Advantages
- Easy maintenance: Benefit from an adjustable upper seal design, allowing for leak repairs without the need for complete disassembly, enhancing efficiency.
- Upgradability: Offers manual operation with the option for pneumatic actuators, facilitating automated control and future-proofing your operations.
- Certifications: Features ISO 5211-compliant mounting pads for direct actuator installation, effectively reducing accessory costs.
