What Is Manual Valve?

Manual valve is a valve operated by hand — typically via a handwheel, lever, or gear — to start, stop, or regulate the flow of liquids, gases, or slurries in a pipeline. Unlike automated valves that rely on electric or pneumatic actuators, manual valves require direct physical operation and do not need an external power supply or control signal to function.

VINCER manual valves are widely used as isolation valves, shut-off valves, and throttling valves in industrial piping systems. They are chosen for locations where automated control is not required, where power supply is unavailable, or where manual override capability is needed as a backup to automated valve systems. Their simplicity, reliability, and low maintenance requirements make them a standard component in virtually every industrial facility.

Quick Quote Guide: How to Select Your Manual Valve

Providing the following information will help us recommend the right valve type and configuration, and return an accurate quotation quickly.

  • Valve type: Specify whether you need a ball valve, butterfly valve, gate valve, knife gate valve, globe valve, or check valve based on your required function (isolation, regulation, or non-return).
  • Pipe size and pressure rating: Provide the nominal pipe diameter (DN or inches) and the required pressure class (PN rating or ANSI/API class). This determines the valve body wall thickness and flange drilling pattern.
  • Connection standard : Indicate the applicable piping standard: GB, ANSI, DIN, JIS, or API. For flanged valves, confirm the flange pressure class (e.g., PN16, Class 150, 10K).
  • Body material: Specify based on your process media and operating temperature. WCB is standard for water, steam, and oil service; SS316/316L for corrosive media; low-temperature carbon steel or stainless steel for cryogenic applications.
  • Process conditions: Provide the working fluid, operating temperature, and maximum working pressure. For special applications (oxygen, ammonia, cryogenic, or hazardous media), please flag this clearly so we can confirm the appropriate valve design and material specification.
  • Quantity and delivery requirements: Standard catalogue products are available from stock or with short lead times. For large-quantity orders or custom specifications, lead times will be confirmed at the time of quotation.
