Key Features

Corrosion Resistance
One of the standout features of Hastelloy is its outstanding resistance to corrosion. This makes it an excellent choice for industries dealing with harsh chemicals and environments.
Temperature Tolerance
Hastelloy valves can withstand a wide range of temperatures. With a melting point of 1260°C, they can handle both low and high-temperature applications.
Strength and Pressure Resistance
The material is very strong, making Hastelloy valves ideal for high-pressure applications, such as in the oil, gas, and chemical industries. However, this strength also means that the valves are relatively heavy, with a density of 8890 kg/m³.
Advanced Design Features
These valves come with an ISO 5211 direct mounting pad for easy actuator installation, a blow-out-proof stem for added safety, lockout capability for secure operations, and high-cycle, live-loaded stem packing to maintain a consistent seal over numerous cycles.

Types of Hastelloy Valves

A Hastelloy ball valve is a type of valve that uses a ball-shaped component to control the flow of fluids. The ball has a hole through its center, called a bore. When the hole lines up with the flow path, fluid passes through. The ball is positioned between valve seats, which help to seal the valve when closed.
 
The ball’s position is controlled by either an actuator or a handwheel, allowing or stopping the flow. This valve is versatile and can be used with vapors, gases, and liquids.

How Does the Hastelloy Ball Valve Work?

The Hastelloy ball valve works by turning a handwheel to control the flow of fluid. When you turn the handwheel 90 degrees counterclockwise, the ball inside the valve rotates so that the hole in the ball lines up with the pipe. This opens the valve and lets the fluid flow through.
 
Turning the handwheel 90 degrees clockwise makes the ball rotate again, but this time, the hole becomes perpendicular to the pipe, closing the valve. The ball and the valve seat create a tight seal to stop any fluid from passing through.
Advantages of Hastelloy Ball Valves
  • Quick and easy to operate.
  • Simple and compact design.
  • Available in various sizes.
  • Causes low pressure drop.
  • Easy to install and repair due to its simple design.
Disadvantages of Hastelloy Ball Valves
  • Quick opening and closing can cause water hammer and overpressure.
  • Not suitable for throttling applications.

Hastelloy Plug Valve

A Hastelloy plug valve controls fluid flow using a cylindrical or conical plug with a central hole. The valve opens and closes by turning a handwheel or using an electric or pneumatic actuator connected to the plug by a stem. It’s versatile, accommodating various flow rates and pressure levels due to its range of sizes.

The Hastelloy plug valve operates by turning the plug at a quarter-turn angle, similar to a ball valve. When you turn the handwheel 90 degrees, the plug inside the valve rotates so that the hole aligns with the pipe, allowing fluid to flow through.
 
Turning the handwheel another 90 degrees in the opposite direction rotates the plug again, making the hole perpendicular to the pipe, which closes the valve. The plug and valve seat fit together tightly to stop the flow. Some Hastelloy plug valves have more than one hole, allowing for multiple flow paths, depending on the plug’s position.
Hastelloy Valves 26
Hastelloy Valves 27
Advantages of Hastelloy Plug Valves
  • Simple and compact design.
  • Easy to operate.
  • Few moving parts, making them easy and affordable to maintain.
  • Low resistance to fluid flow, resulting in a low-pressure drop.
  • Easy to install, clean, and repair.
Disadvantages of Hastelloy Plug Valves
  • Not ideal for throttling applications.
  • Requires high torque to operate.
Hastelloy Valves 28
Hastelloy Check Valve

A Hastelloy check valve is a type of valve that prevents fluid from flowing backward. It’s also called a non-return valve or one-way valve because it only lets fluid flow in one direction. If the fluid tries to flow in the reverse direction, the valve closes automatically. Unlike other valves, a Hastelloy check valve doesn’t have a stem, handwheel, or actuator. It’s designed to open and close on its own based on the fluid pressure.

How Does a Hastelloy Check Valve Work?
A Hastelloy check valve works based on pressure differences. When the pump starts or the pressure on the upstream side (the side before the valve) becomes higher than the downstream side (the side after the valve), the valve disc lifts, allowing fluid to flow through.
 
If the pump stops or the upstream pressure drops below the downstream pressure, the valve disc quickly moves down and closes, stopping any fluid from flowing backward. This type of valve is ideal for applications that require high levels of hygiene or where there is a risk of the downstream fluid contaminating the upstream fluid.
Hastelloy Valves 29
Advantages of the Hastelloy Check Valve
  • Operates automatically.
  • More affordable compared to other valves.
  • Causes a low-pressure drop.
  • Quick to operate.
  • Prevents reverse flow.
Disadvantages of Hastelloy Check Valves
  • Can cause water hammers due to fast closing and opening.
  • Not suitable for pulsating flow.
Hastelloy Gate Valves

A Hastelloy gate valve controls fluid flow by lifting a component called the gate or disc. When the gate moves down into the seat, it stops the flow of fluid. This type of valve takes up little space along the pipe and doesn’t restrict flow when fully open. It can be operated manually with a handwheel or automatically with an electric or pneumatic actuator, giving users flexibility in how they control the valve.

Hastelloy Valves 30
Hastelloy Valves 31
How Does a Hastelloy Gate Valve Work?
The Hastelloy gate valve works by turning the handwheel several times. When you turn the handwheel counterclockwise, the valve stem moves upward, lifting the gate or disc, which opens the valve and allows fluid to flow through.
 
Turning the handwheel clockwise lowers the stem and the gate back into the seating position, closing the valve and stopping the fluid flow. It’s important to note that this valve is not designed for throttling, as high pressure and flow can wear down the gate and cause damage.
Advantages of Hastelloy Gate Valves
  • Suitable for high-pressure and high-temperature applications.
  • Causes a low-pressure drop when fully opened.
  • Allows for bi-directional flow.
Disadvantages of Hastelloy Gate Valves
  • Not ideal for throttling fluid flow.
  • Slow to operate; the handwheel must be turned several times to open or close the valve.

Hastelloy Globe Valve

A Hastelloy globe valve has a rounded, spherical body and uses a disc to control the flow of fluid. This valve is especially good for adjusting the flow, making it the best choice for throttling compared to other valves. It can be operated manually with a handwheel or automatically with an electric or pneumatic actuator.
 
Unlike the Hastelloy gate valve, the globe valve opens and closes more quickly, requiring fewer turns. However, this design can cause higher pressure drops, and the internal components make it more complex.
 
The Hastelloy globe valve works by turning the handwheel either clockwise or counterclockwise. Turning the handwheel counterclockwise raises the valve stem and disc, opening the valve to allow fluid to flow. Turning the handwheel clockwise lowers the stem and disc, closing the valve and stopping the flow. For throttling, you can turn the handwheel slightly counterclockwise to allow partial flow through the valve.
Hastelloy Valves 32
Hastelloy Valves 33
Advantages of Hastelloy Globe Valves
  • Excellent for throttling fluid flow.
  • Faster to operate compared to gate valves.
  • Provides a tight seal with no leakage.
Disadvantages of Hastelloy Globe Valves
  • Causes a high-pressure drop.
  • Heavier than other types of valves.
