Product Selection Differences for Butterfly Valves with Manual Actuators

When selecting butterfly valves with manual actuators, there are several key differences to consider among available options. These differences can impact the performance, durability, and functionality of the valves. Here are some factors to consider:

Material: Butterfly valves can be made of various materials such as stainless steel, carbon steel, PVC, and others. The material choice will depend on the specific application requirements, fluid characteristics, and environmental conditions.
Size and Pressure Rating: Butterfly valves come in a range of sizes and pressure ratings. It is essential to select a valve size and pressure rating that is suitable for the intended application to ensure proper performance and safety.
Type of Actuator: Manual actuators for butterfly valves include lever handles, gear operators, and handwheels. The type of actuator chosen will depend on ease of operation, available space, and operator preference.
Sealing Design: Butterfly valves can have different sealing designs such as resilient (rubber) seats or metal seats. The choice of sealing design will affect the valve's performance in terms of leakage, pressure capabilities, and temperature range.
Flow Control and Performance: Consider the flow control characteristics of the butterfly valve, such as throttling capability, flow capacity, and pressure drop. Select a valve that can meet the specific flow control requirements of the application.
Corrosion Resistance: Depending on the application environment, it's important to consider the corrosion resistance of the valve materials to ensure longevity and reliability.
Certifications and Standards: Ensure that the butterfly valve and manual actuator meet industry standards and certifications to guarantee quality, safety, and compliance with regulations.

By carefully considering these factors, you can choose the most suitable butterfly valve with a manual actuator for your specific application requirements.
