Cannabis concentrate production has become a rapidly growing industry, with increasing demand for high-quality products. In order to achieve product consistency and reliable results, it is essential to have the right equipment for the job. 

Valves and flow meters are critical components in the cannabis extraction process, helping to regulate the flow of materials and ensure accurate measurements. Choosing the right valves and flow meters can have a significant impact on the efficiency and effectiveness of your cannabis extraction operation. 

Here, we will discuss tips for selecting the appropriate valves and flow meters and the advantages of using high-quality materials. We will also cover best practices for maintaining and caring for valves and flow meters to optimize your cannabis concentrate production.

Types of Valves Used for Cannabis Concentrates

Valves are crucial components in the cannabis extraction process. As a cannabis extractor, you can choose from various types of valves used in the industry. Each type of valve has unique characteristics that make them suitable for specific applications.

Ball Valves

Ball valves are known for their reliability and versatility. They have a simple design, consisting of a ball with a hole in the middle that can be rotated to control the flow of materials. Ball valves are often used in situations where the control of flow is required. In cannabis extraction, ball valves may be used to control the flow of solvents or gases.

Ball valves are designed with a simple construction that makes them easy to disassemble and clean, reducing the risk of contamination and ensuring consistent results. However, they offer limited flow control compared to other valves and there is a risk of leakage over time due to wear and tear on the ball and seats.

Gate Valves

Gate valves are ideal for regulating the flow of larger particles, making them a good choice for cannabis extraction processes that involve plant material. They have a sliding gate that can be moved to open or close the valve, allowing for precise control of flow. Gate valves are often used in situations where there is a risk of clogging or blockage, as they are less likely to become obstructed than other types of valves.

Gate valves typically have a lower pressure drop compared to other types of valves, which can be advantageous for applications where maintaining pressure is important. Gate valves are designed to provide a tight seal when closed, which can help to prevent leaks and contamination.

However, they may not be suitable for high-pressure applications, as they can become stuck or damaged under high-pressure conditions. They may also not be as effective for fine-tuning flow rates over a wide range.

Butterfly Valves

Butterfly valves are often used for their ability to provide a tight seal and precise control of flow. They have a disc-shaped closure that is rotated to control the flow of materials. Butterfly valves are commonly used in situations where a low profile and quick on/off control is needed. In cannabis extraction, butterfly valves may be used to regulate the flow of gases or liquids during the extraction process.

Butterfly valves are lighter in weight compared to other types of valves, which can help in situations requiring portability or ease of installation. They’re also cheaper than ball valves of a similar size. They also have a lower pressure drop compared to other valves.

Butterfly valve disadvantages include reduced flow capacity and flow control, which can be detrimental in high flow rate applications.

Needle Valves

Needle valves are another type of valve that may be used in cannabis extraction processes. They have a long, tapered point at the end of a valve stem that is used to control the flow of materials. Needle valves are ideal for situations where precise control of flow is required, as they allow for fine adjustments to the flow rate.

Needle valves are easily adjusted to fine-tune flow rates and are often made from high-quality materials such as stainless steel. However, they have a limited flow capacity and limited pressure range compared to other valves, and are prone to clogging due to the narrow openings.

Digital Flow Meters vs. Mechanical Flow Meters

In addition to choosing the right type of valve for cannabis extraction, it is also important to consider the type of flow meter that will be used to measure the flow rate of materials. There are two main types of flow meters: digital flow meters and mechanical flow meters.

Digital Flow Meters

Digital flow meters use electronic sensors to measure the flow rate of materials. They are highly accurate and provide real-time data that can be easily monitored and recorded. Digital flow meters are often used in situations where precise control of flow is required. They can be programmed to send alerts if the flow rate falls outside of a specified range, which can help to prevent equipment damage or product loss.

Mechanical Flow Meters

Mechanical flow meters use a mechanical mechanism to measure the flow rate of materials. They are typically less expensive than digital flow meters, but they may not provide the same level of accuracy or real-time monitoring. Mechanical flow meters are often used in situations where the flow rate does not need to be closely monitored or where cost is a primary consideration.

Importance of Quality Materials in Cannabis Extraction Equipment

The quality of materials used in cannabis extraction equipment can have a significant impact on the efficiency and effectiveness of the extraction process. It is essential to select equipment made from high-quality materials that can withstand the harsh conditions of cannabis extraction and ensure you extract the valuable compounds found in the cannabis/hemp plant.

PVC Valves

Polyvinyl chloride (PVC) valves are a popular choice for cannabis extraction operations due to their lightweight, affordable, and easy-to-install nature. They are suitable for low-pressure applications and work well with mild solvents. 

However, PVC valves are not as durable as stainless steel valves and may not be compatible with certain aggressive chemicals and solvents. It is important to consider the type of solvent or chemical you will be using in your extraction process when choosing a valve material.

Stainless Steel Valves

Stainless steel valves are widely used in cannabis extraction operations due to their durability, resistance to corrosion, and ability to withstand high temperatures and pressures. They are suitable for use with aggressive solvents and chemicals, making them an ideal choice for cannabis concentrate production. 

Stainless steel valves come in different grades, with 316L being the most commonly used in the cannabis industry due to its high resistance to corrosion and compatibility with most solvents and chemicals.

Maintaining and Caring for Valves and Flow Meters in the Cannabis Industry

Proper maintenance and care of the extraction system, including valves and flow meters, is essential for ensuring consistent and reliable results. Here are some tips for maintaining and caring for your valves and flow meters:

Regular Cleaning

Regular cleaning of valves and flow meters is extremely important for preventing contamination and ensuring accuracy. Use appropriate cleaning agents and follow manufacturer's instructions for proper cleaning procedures.

Inspections

Regular inspections of valves and flow meters can help identify any issues before they become bigger problems. Inspect valves and flow meters for signs of wear or damage, and replace as necessary.

Lubrication

Proper lubrication of valves and flow meters can help to prevent damage and ensure smooth operation. Use lubricants recommended by the manufacturer and follow instructions for proper application.

Calibration

Regular calibration of flow meters can help ensure accurate measurements. Follow the manufacturer's instructions for proper calibration procedures.

Replacement of Worn Parts

Worn or damaged parts can lead to inaccurate measurements and reduced product quality. Replace worn or damaged parts as necessary.

Proper Storage

Proper storage of valves and flow meters is important for preventing damage and ensuring accuracy. Store valves and flow meters in a clean, dry, and secure location.
