alfa laval safety valve brands

It is used to prevent inadmissible overpressures of fluids in tanks, containers, and plant sections. From the factory, the valve is configured with a set pressure upon request that is created than the operating pressure. The valve opens against a spring force if the operating pressure increases the set pressure. Preferably, the Alfa Laval Safety Valve should be installed vertically. If mounted horizontally the set pressure will be a bit lower than specified due to the missing weight of the piston.

The metal stem plug of the relief valve is held in the closed position by manually adjusted spring tension. As the pipe line pressure increases beyond the spring"s relief set point, the stem plug is forced open, allowing pressure to be relieved through the discharge port. As the pressure lowers below the spring set point, the plug will return to the closed position.

The compression valve is operated by means of a "tee" handle turning mechanism. This allows the valve to gradually open and close.OPTIONSPressure range springs (relief spring chart above)

January 19, 2016 - Alfa Laval announces Safety Valves that protect against overpressure in tanks and pipelines caused by overfilling or fermentation processes.

In a potentially dangerous situation it will open at a predetermined set pressure. The compressed spring force, keeping the valve closed, is forced open when pressure builds up at the inlet of the safety valve. As these forces balance out, the valve will discharge and decrease pressure, ultimately reclosing as the system returns to normal.

These safety valves protect also protect against implosion due to vacuum caused by cold rinsing after hot cleaning or blocking of gas supply during emptying.

The Alfa Laval safety valve can be combined with the Alfa Laval SB anti vacuum house into a combined safety valve, protecting against both vacuum and overpressure in one hygienic valve solution with a single tank connection.

A compact safety valve that minimizes the risk of implosion of tanks when a vacuum condition arises. These conditions occur while filling or emptying the vessel of liquid, cool rinsing after hot-cleaning or caustic cleaning in a CO2 atmosphere. Designed for use in the brewery, dairy, food and beverage industries, it helps optimize the safety, reliability and performance of critical processes and maximize uptime.

The Alfa Laval SB Anti Vacuum House minimizes the risk of implosion in closed process tanks that are subject to vacuum conditions, such as while filling or emptying the tank, cool rinsing after hot-cleaning, or caustic cleaning in a CO2 atmosphere. Capable of being integrated into a SCANDI BREW® tank top system, the valve is designed for hygienic processes in the brewery, dairy, food and beverage industries.

Pressure can build inside vessels or systems due to blocked discharge, thermal expansion, chemical reactions, or a combination of these events. The Alfa Laval Safety Valve is designed to flexibly relieve excess pressure from vessels or equipment at all times and under any circumstances. As the last and vital component in accident prevention, a high-quality, hygienic safety valve is an essential part of your operations.

Depending on the causes of excess pressure, a different mass or volume flow may need to be discharged. With this type of variable flow, a perfectly fitted safety valve is essential. The Alfa Laval Safety Valve comes in sizes from DN25 to DN100 with a spring-loaded set pressure range between 0.2 and 12.0 bar depending on the size of the valve.

In a potentially dangerous situation, the Alfa Laval Safety Valve is designed to open at a predetermined set pressure. The compressed spring force, which keeps the valve closed below the set pressure, is forced open when pressure builds up at the inlet of the safety valve. As these forces balance out, the valve will discharge and decrease pressure, ultimately reclosing as the system returns to normal.

To prevent damage to the tank and help ensure safe operations, the Alfa Laval SB Pressure Relief Valve protects a pressurized tank during an overpressure event. It is designed for hygienic processes in the brewery, dairy, food and beverage industries. The valve can be integrated with a SCANDI BREW® tank top system.

This pressure relief valve removes excess liquid that creates overpressure in the tank due to overfilling. When pressure in the tank exceeds a preset value, the pressure relief valve opens to vent fluid in the event of liquid overfilling, and closes when the tank pressure has returned to a safe level.

Few moving parts and smooth, crevice-free stainless steel surfaces make this valve easy to clean. When the valve is in closed position, it is cleaned as part of the routine Cleaning-in-Place (CIP) cycle. For thorough cleaning of the valve seat, an optional pneumatic force opener and a splash guard is available.

The Alfa Laval SCANDI BREW® Pressure Relief Valve is a hygienic safety valve. This Flange Mounted Valve is designed with a counterweight, which is set and locked at the desired pre-set pressure value for tanks and vessels used in hygienic process lines in the brewery, dairy, food, beverage and many other industries. The valve can also be integrated onto a tank top system.

They combine the innovation of Alfa Laval with the time-proven reliability of Tri-Clover brand valves, providing the options required to meet your processing needs.

From compression and relief valves to sampling and CPM valves, Alfa Laval has the products and technology to provide you with sanitary, efficient and economical valve solutions to suit your unique application.
