Butterfly or gate valve suitable for water mains?

In the water pipeline configuration, butterfly valves and gate valves have their own advantages: butterfly valves are lightweight and low-cost, suitable for flow regulation and frequent opening and closing; gate valves are strong and stable, but more laborious and costly to operate. The choice should be based on flow control needs, frequency of operation, budget and long-term maintenance costs.

Types of valves commonly used in water supply systems

This article analyzes the water supply system five core valve types and applications: ball valves (reliable sealing, fast opening and closing, suitable for small and medium-sized pipeline cut-off); butterfly valves (lightweight and easy to operate, the main control of large flow regulation); gate valves (durable full diameter, used for the main pipeline opening and closing); check valves (to prevent the medium from backing up, to protect the safety of water pumps); regulating valves (accurate control of the flow control pressure, adapt to the precision of the water supply scenarios). Scientific selection can improve system efficiency and water supply safety.

What common types of drain valves include

This article takes a look at the common types of sewage valves and their application scenarios: gate valves (low flow resistance, suitable for large flows of solids-containing wastewater); butterfly valves (compact, lightweight and quick to operate, suitable for wastewater treatment); ball valves (excellent sealing, low flow resistance, suitable for viscous/crystallized media); check valves (to prevent backflow and safeguard pipeline safety); and regulating valves (to control the flow rate/pressure accurately for complex wastewater). Selection should be based on the combination of fluid characteristics (temperature/pressure/chemical composition/solid particles), piping size, and operation and maintenance, in order to enhance the efficiency of wastewater discharge and environmental safety.

Butterfly valve can withstand how high temperature limit

This paper analyzes the limit of high temperature resistance of butterfly valve and key influencing factors. Temperature resistance depends on material, technology and seal structure:
EPDM Seal: -20℃~120℃
Nitrile rubber seal: 0℃~80℃
Teflon sealing: 0℃~150℃
Stainless steel seal: -29℃~425℃ (optimal temperature resistance)
The actual selection needs to synthesize the fluid type, pressure, temperature fluctuations and other working conditions to ensure stable operation in high temperature environments.

Types of valves commonly used in building water supply system

This article introduces the six commonly used valves and their functions in the building water supply system: ball valves (easy to operate, open and close quickly for hot and cold water pipelines), butterfly valves (compact structure, suitable for large flow mains), globe valves (low fluid resistance, adjustable flow), check valves (to prevent backflow, to protect the pumps), regulating valves (to accurately control the flow rate) and pressure reducing valves (to reduce the pressure, to protect the safety of equipment). Engineers need to choose the right valve according to system requirements, operating characteristics and environmental factors to ensure efficient and stable operation of the system.

Commonly used types of manual valves

Manual valves are key control elements in the pipeline fluid transportation system, widely used in industrial fields, designed to ensure smooth fluid transportation and safe operation of the system. This article focuses on four common types: manual butterfly valve (simple structure, convenient operation, divided into handle type and worm gear type, applicable to different caliber pipeline), manual gate valve (commonly used in water distribution system, divided into open rod and concealed rod type, opening and closing status intuitive), manual ball valve (used to cut off the flow, shunt and adjust the direction of flow, opening and closing parts for the ball) and manual disconnecting valve (good abrasion resistance, maintenance is convenient, but opening and closing torque, nominal diameter). (≤200mm). Selection needs to be based on the pipeline characteristics and working environment to ensure that the system is efficient and stable.

Analyzing the applicability of butterfly valves as control valves

This paper evaluates the suitability of butterfly valves as regulating valves for fluid management in the industrial and construction sectors. The advantages of butterfly valves include simple design, small size, light weight, easy installation and maintenance, low operating torque, fast response and low flow resistance, which can reduce energy consumption and cost. However, its regulating precision is insufficient, the flow characteristic curve is nonlinear, it is easy to cause flow fluctuation when small opening, and the seal may decline and lead to leakage in long-term use. Therefore, butterfly valves are suitable for scenarios (such as ventilation or water supply and drainage systems) that do not require high regulation accuracy, have a wide range of flow variations, and emphasize cost and convenience; however, for high-precision demand scenarios (such as chemical production), ball valves or precision control valves are recommended.
