Types of Keys for Valves and Pumps

1. Square Keys

Square keys, also known as square shaft keys or straight keys, are simple and widely used keys in valve and pump applications. They have a square cross-section and fit into corresponding keyways on shafts and hubs, providing rotational torque transmission and preventing slippage.

2. Woodruff Keys

Woodruff keys are semi-circular keys with a flat or curved bottom and a rounded top. They are commonly used in applications where the keyway is machined into a shaft, and the key slides into the keyway on a hub or wheel. Woodruff keys provide a positive drive while allowing for axial adjustment.

3. Gib Head Keys

Gib head keys, also known as taper keys, have a tapered shape with a larger head at one end. They are primarily used for heavy-duty applications that require a strong and secure connection. Gib head keys are inserted into tapered keyways, and their taper provides self-locking and prevents the key from loosening under load.

4. Feather Keys

Feather keys, also called parallel keys or machine keys, have a rectangular or square cross-section with rounded corners. They are commonly used in valve and pump applications to transmit torque between shafts and hubs. Feather keys provide precise alignment and prevent rotational movement.

5. Saddle Keys

Saddle keys, also known as saddle anchors or half-moon keys, have a saddle-shaped profile with a flat top and rounded sides. They are used in applications where a keyway is machined on the shaft and the key fits into a corresponding keyway on the hub or wheel. Saddle keys provide excellent torque transmission and resist axial movement.

6. Tangential Keys

Tangential keys, also called round-end keys or circular keys, have a cylindrical shape with a rounded end. They are used in applications where the keyway is machined on the shaft and the key fits into a circular groove on the hub. Tangential keys transmit torque and resist axial movement effectively.

Keys for valves and pumps are specialized components used to connect rotating shafts with other parts, such as hubs, gears, or impellers. These keys play a crucial role in transmitting torque, preventing slippage, and ensuring proper alignment and operation of valves and pumps.
Keys for valves and pumps can be manufactured from various materials, including steel, stainless steel, brass, or other suitable alloys. The material selection depends on factors such as the application’s load requirements, environmental conditions, and compatibility with the shaft and hub materials.
Selecting the appropriate keys involves considering factors like the shaft and hub dimensions, keyway specifications, torque requirements, and the operating conditions of the valve or pump system. Collaborating with key manufacturers or consulting engineering experts can aid in selecting the suitable keys for a specific application.
Yes, keys for valves and pumps can be customized to meet specific application needs. Manufacturers often provide customization options in terms of key type, dimensions, materials, and other specifications. Customized keys ensure proper fitment, alignment, and optimal performance in valve and pump systems.
The keys are meticulously crafted to achieve a precise fit and alignment within the keyways of valves and pumps. This tight fit enhances the overall performance of the systems by minimizing play, reducing vibration, and optimizing power transmission.
The keyway cut into the shaft reduces the load carrying capacity of the shaft. This is due to the stress concentration near the corners of the keyway and reduction in the cross-sectional area of the shaft i.e. the torsional strength of the shaft is reduced.

It is basically designed for opening and closing of valve by simply turning or twisting with the help of offered valve key. This tool is provided with long handle equipped with rubber grips for easy and strong handling further makes manual operation very much simple and easy. We have designed the offered key in varied models and specifications with respect to the valve size so that clients can buy as per requirement.
