MIWIVAL Vacuum Relief Valve

Setting Pressure: -500mba!

Vacuum relief valves are protection devices which are typically mounted on a nozzle opening on the top of a fixed roof storage tank.
It is primarily used as a device for relieving vacuum in tanks, containers and process engineering equipment. 

The valve offers reliable protection against vacuum, and prevents inbreathing of air close to the set pressure.

MIWIVAL Automatic Float Valve for Water Tank Level Control

• Controls the level of the fluid in a deposit.
• 100% Water tight.
• Working temperature between -10ºC and 90ºC.

Float valves, used to automatically keep the level of the fluid in a deposit. The float can be installed in the distance so the valve can be integrated in the pipeline next to the deposit.
• Sizes: DN: 50-300
• Pressure design (bar): 10-16

MIWIVAL Pilot-Operated Pressure Reducing Valves for Steam

In a steam-using plant, steam is often generated at high pressures and reduced locally to provide heat for each steam user. This is usually done to minimize the diameter of steam distribution piping and enable more cost-efficient steam delivery.
Pilot-Operated Pressure Reducing Valve: Adjustment spring places downward pressure setting force directly on a pilot valve, which is smaller and different from the main valve.
