Product Description

 Sanitary Grade Stainless Steel 316L Clamp Manual Butterfly Valve With Plastic Regulating Handwheel

 

A is a hygienic flow control device designed for precise throttling of liquids in clean process systems. It is commonly used in food, beverage, dairy, pharmaceutical, and biotech industries where cleanliness and accuracy are critical. The valve's design minimizes dead zones and allows for easy cleaning, making it ideal for CIP/SIP environments. Its ability to control flow rates with minimal pressure drop ensures consistent product quality while maintaining sanitary standards across the production line.

Working Principle
The stainless steel sanitary regulating butterfly valve operates by rotating a disc within the flow path to precisely adjust flow. When the handle or actuator turns the shaft, the disc changes angle to regulate liquid passage. At partial openings, it allows fine throttling; at full open, it minimizes restriction. The valve uses a centralized seal to prevent leakage, and its smooth internal surfaces reduce contamination risk. Integrated position indicators and CIP-friendly design ensure accurate control and hygienic maintenance throughout processing.

Product Description

Stainless steel sanitary valves are widely used in high-cleanliness industries and have the following significant feature:
1. Notched Disc Throttle Control
The disc has preset notches for positioning. It allows operators to precisely control flow rate in small increments, ideal for dosing and fermentation.

2. Strengthened Shaft Design
A thick shaft with dual O-rings ensures better durability and sealing, especially under repeated actuation in automated systems.

3. Offset Seal Seat Profile
Asymmetrical seat geometry gives balanced pressure during opening, offering improved sealing without excessive seat stress.

 

4. Self-Centering Shaft Support
Internal guides align the disc automatically, resulting in smoother, low-torque rotation during operation and reduced wear.

5. CIP-Ready Stem Channels
Hidden CIP grooves clean around the stem, ensuring hygienic performance by flushing hard-to-reach sealing areas.

6. ISO/DIN Mounting Interface
Universal actuator base supports both standards, enabling fast integration into global control systems with minimal rework.
