Vacuum Exhaust PVRV Valves

Introduction to functions and features

The valve is applied to a pressure vessel type piping system. The breathing valve has two functions. When the pressure is higher than the set pressure (standard 1BAR), it can be vented, and vice versa. When the vacuum is generated in the piping system (standard -0.2BAR) When the valve is automatically opened to ensure the safety protection of the equipment and related instruments, it can also meet the needs of various production processes. The valve is made of stainless steel and hygienic design, which is suitable for various food processing, beer, beverage and pharmaceutical industries. Industrial field.

Operation process:

 1. When the valve is closed, the spring presses the disc against the main port, keeping the medium in the container

2. When sampling, just turn the handwheel

3. The valve disc is disconnected from the main port, allowing the medium to flow into the sample chamber

4. After injection, turn the handwheel to close the valve

5. The medium sample flows out of the branch port for inspection

6. Pour clean water into the sample valve to clean the sampling chamber.

Technical parameters: Interface: clamp Pressure: 0.2mpa Temperature: -30C. +150c. Working medium: gas

The company has always implemented the business philosophy of "survive by quality, develop by technology, benefit by management, and consolidate by credit". The product quality meets the requirements of the industry and is sold to Europe, America, Southeast Asia, the Middle East and other countries and regions.

Vacuum Exhaust PVRV valves, also known as Pilot Operated Vacuum Relief Valves, are used in various industries to protect vessels from incurring damage due to negative pressure created by a vacuum. These valves are designed to prevent vacuum buildup through the removal of excess gas or air from the system. work by opening automatically when the pressure inside a vessel drops below atmospheric pressure, allowing air or gas to flow into the system, thus preventing the formation of a vacuum.

 are commonly used in the petrochemical, oil and gas, and pharmaceutical industries. They are often installed in storage tanks, reactors, and pipelines to prevent damage to equipment and ensure a safe working environment. These valves are designed to operate in extreme temperatures and harsh environments, ensuring that they can withstand the rigors of everyday use.

The vacuum relief valve is a crucial component in many industrial processes, and its failure can lead to potentially catastrophic consequences. The use of  ensures the safe and effective running of many different types of machinery and equipment. In addition, these valves are regularly tested and inspected to ensure they continue to operate effectively and reliably. 

Vacuum safety valve product use:

For normal non-negative pressure system: various corrosive medium containers, such as absorption towers, distillation towers, storage tanks, tanks, etc., when the steam is cleaned, if the discharge valve is not opened, the steam condenses, generating negative pressure, Installing the device ensures that the device is safe.

1.Widely Usage:Suitable for beer, beverage, dairy, edible oil, biological, pharmaceutical, textile, chemical and other industries.

2.Functions of Exhalation and Inhalation:The valve has the functions of exhalation and inhalation, which greatly reduces the cost and installation space, and ensures the safety of the system of the container and the pipeline.

3.Safe to Use:When the internal pressure of the vessel is higher than the set pressure, the valve will automatically open to vent outside the vessel, otherwise the valve will close.

4.Not Easy to Deform:When a negative pressure is generated in the container, the valve will automatically open to inhale into the container; prevent the container from deforming.

5.Package Including:1 x Pressure Reducing Valve.
