Core Advantages: Engineering & Technical Highlights
• Zero-Dead-Leg Hygienic Design: Highly polished flow passages with no gaps or recesses eliminate product residue, fundamentally removing breeding grounds for microorganisms and ensuring compliance with sanitary standards.
• Superior Cleaning Tolerance: Seals feature a high-performance, food-grade elastomer formula capable of withstanding repeated exposure to strong alkaline washes, acid disinfectants, and high-temperature steam without chemical decomposition or odor release.
• Compact & Lightweight Structure: Minimal mechanical components and a short face-to-face length significantly reduce piping space requirements, facilitate easy on-site installation and disassembly, and lower overall structural load.
• Precise Multi-Position Throttling: The manual version is equipped with a robust multi-position pull lever or notched positioning handle for precise, stepped flow regulation. Designed with a standard top interface to easily allow future automated upgrades to pneumatic or electric smart actuators.

Selection & Installation Engineering Guide
To ensure optimal hygienic performance and service life, please refer to the following engineering parameters when selecting and installing:
1. Seal Material Selection (Chemical & Temperature Matching)
Selecting the right elastomer material is critical to preventing pipe contamination caused by seal swelling or degradation:
EPDM (Ethylene Propylene Diene Monomer): The standard choice for general-purpose food lines. Excellent resistance to hot water, steam, and polar fluids. Not suitable for fatty or oily media.
Silicone (VMQ): Offers a wide temperature range and exceptional elasticity. Ideal for fine foods, beverages, and biopharmaceuticals. Lower resistance to high-concentration alkaline solutions.
Fluoroelastomer (FKM/Viton): The preferred material for high-fat contents, vegetable oils, animal fats, and high-temperature concentrated flavorings.
2. Sizing & Flow Velocity Matching
Sanitary lines are typically designed around specific flow velocities to maintain self-cleaning effects during CIP cycles (generally controlled at 1.5–2.1 m/s). Avoid oversizing the valve; a partially open disc under low flow velocity can generate local eddies, causing uneven wear on the rear of the elastomer liner.
3. Thermal Expansion & Tri-Clamp Alignment
When using hygienic Tri-Clamp or welded connections, precise pipe alignment is essential. Pipe misalignment or excessive thermal stress creates torsional forces that deform the valve body out-of-round, increasing disc operating torque, accelerating actuator wear, and prematurely tearing the elastomer liner.
4. Orientation & Full Self-Draining
To ensure complete system drainage during CIP cycles (achieving zero liquid retention), it is recommended to install the valve stem horizontally rather than vertically. This orientation allows fluid to flow freely from the bottom edge of the disc when slightly cracked open, preventing liquid entrapment at the bottom of a vertical stem.
