Manual Butterfly Valve - Ningjin Thriveon Valve | Features, Applications

Introduction

Manual Butterfly Valves are essential components in various industrial and commercial applications, offering a reliable and cost-effective solution for fluid control. Unlike their automated counterparts, these valves are operated manually, typically through a lever or gear mechanism, making them ideal for scenarios where simplicity and ease of maintenance are prioritized. This article provides an in-depth analysis of the **Manual Butterfly Valve**, covering its features, technical specifications, applications, and the company behind its production.

Product Overview

A **Manual Butterfly Valve** is a type of quarter-turn valve that uses a disc to control the flow of fluids within a pipeline. The term "manual" refers to the fact that these valves are operated manually, as opposed to **pneumatic** or **electric actuators**. This design simplifies the valve's structure, making it more compact, lightweight, and easier to install. According to the product description, manual butterfly valves are particularly suited for applications requiring straightforward operation without the need for external power sources.

Key types of manual butterfly valves include **lever-operated** and **gear-operated** variants. While both are manual, gear-operated valves offer enhanced torque control, making them suitable for higher-pressure environments. This distinction is crucial in selecting the right valve for specific industrial needs.

Comparing Manual and Pneumatic Actuated Butterfly Valves

Manual butterfly valves differ significantly from **pneumatic actuated butterfly valves** in terms of complexity and functionality. Pneumatic actuators rely on compressed air to operate, providing automated control but requiring additional infrastructure. In contrast, manual valves are simpler in design, with fewer components, which reduces the likelihood of mechanical failure and lowers maintenance costs. As noted in the product FAQ, manual butterfly valves are "convenient to install" and "have a simple structure," making them a preferred choice for many applications.

Key Features and Advantages

The **Manual Butterfly Valve** is renowned for its **durability**, **ease of installation**, and **cost-effectiveness**. Here are some of its standout features:

• Simple Structure: The absence of complex actuation systems reduces the risk of mechanical failure and simplifies maintenance.
• Compact Design: Manual valves are typically smaller and lighter than their automated counterparts, saving space in installations.
• Cost-Effective: With fewer components, manual valves are generally less expensive to purchase and maintain.
• Reliable Operation: The straightforward design ensures consistent performance under various operating conditions.

These advantages make manual butterfly valves ideal for applications where automated control is unnecessary, such as in low-pressure systems or where manual oversight is preferred.

Technical Specifications

The **Manual Butterfly Valve** is engineered to meet rigorous industry standards, ensuring compatibility and reliability across diverse applications. Below is a detailed breakdown of its technical specifications:

Parameter	Details
Materials	Body: Grey Cast Iron, Ductile Cast Iron, Stainless Steel 304/316, Carbon Steel Disc: Ductile Cast Iron (Nickel-plated or Nylon coated), Stainless Steel 304/316, Aluminum Bronze Stem: Stainless Steel 410/416/304/316 Seat: EPDM, BUNA-N, PTFE, Viton, Hypalon, Neoprene, Metal Seated
Pressure Ratings	CLASS 125/150; PN10/16/25; 5K/10K/16K
Standards Compliance	API 609, BS5155, MSS SP-67/68, EN593
Installation Guidelines	Space out the flanges to allow the valve to pass easily. The disc should be in a half-opened position. Do not fit gaskets between the flanges. With the disc in a half-opened position, insert all bolts but do not tighten the nuts yet. Open the valve fully to verify pipeline alignment. Tighten the nuts afterward.

Applications and Industry Use Cases

Manual butterfly valves are widely used across various industries due to their versatility and reliability. Some common applications include:

• Water and Wastewater Treatment: These valves are used to control the flow of water and sewage in municipal and industrial systems.
• HVAC Systems: Manual butterfly valves regulate airflow in heating, ventilation, and air conditioning systems.
