Stainless Steel Vacuum Vest Valve

WH-5102

  • Product Introduction

The Stainless Steel Vacuum Vest Valve is a durable and reliable valve used for controlling the flow of gas or liquid in high-pressure applications. Made from high-quality stainless steel, this valve can withstand extremely high temperatures and is resistant to corrosion and abrasion. Its vacuum vest design allows for closed-loop venting, preventing any loss of vacuum during operation. The valve can be easily installed and has a compact design, making it ideal for use in tight spaces. Its precise and smooth operation ensures maximum efficiency, making it a popular choice for use in industries such as chemical processing, oil and gas, and pharmaceuticals.

COMBUSTION RESEARCH ASSOCIATES manufactures Pressure Vacuum Relief Valves (PVRV), Breather Valves, Safety Relief Valves and Vacuum Breaker Valves of wide range to meet the industry requirements.
In case of combustible fluids storage the safety valves should be used along with flame arrestors.


Sanitary Tank Pressure and Vacuum Relief Valves work in the following ways-- From the Vacuum side, when the valve is normally closed and there is vacuum in the tank, the vacuum piston inside the valve opens automatically and draws air into the tank. In return, this keeps the pressure inside and outside the tank balanced. From the Pressure side, when the valve is normally closed and the tank pressure exceeds the rated pressure on the outside of the valve, the valve automatically opens and vents air to atmosphere.

As for installation of the clamp style Tank Pressure and Vacuum Relief Valve, position the valve on the process line and tighten the nut or fasten the clamp according to the fastening system selected and if you are using the clamp style it is recommended to use a clamp gasket and tighten the wing nut of the Heavy Duty Single Pin Clamp to 25 inch pounds of torque.

The calibration range is as follows:

Pressure: 2.8 PSI to 43.5 PSI

Vacuum: 0.15 PSI to 0.75 PSI

The above calibration ranges depend on model and size.



Product Description

Introduce the products and technical data

The valve is used in pressure vessel piping systems.Breathing valve has two functions, when the pressure is higher than the set pressure (standard 1 BAR) can exhaust, whereas closed, while vacuum piping system (standard 0.2 BAR) when the valve opens automatically, to ensure the safety of the equipment and related instrumentation protection, at the same time can also meet the demand in all kinds of production process, the valve in stainless steel material, health design, content with all sorts of food processing, beer, beverage and pharmaceutical and other industries.
