Vent valve interlock for pressure vessels

Mistura Systems has a trapped key interlock valve suitable for venting or purging pressure vessels.

Mistura Systems has a trapped key interlock valve suitable for venting or purging pressure vessels.

Manufactured in polished stainless steel, making it ideally suitable for the food processing industry, the valve protects operators from the dangers of scalding in environments too wet for electrical interlocks.

Pressure cookers, for example, present an obvious danger.

Pressurised water over 100C may not appear to be boiling but if the cooker is opened the water will immediately boil, scalding the operator.

Therefore, before the access hatch is opened, a vent valve must be used to ensure the contents are returned to atmospheric pressure.

The Mistura interlock valve ensures that access can only be achieved when the valve is fully open.

Used in conjunction with an interlock on the access lid, the valve retains the key to the lid while closed.

The key can only be removed when the valve is fully open, venting the pressure vessel to the outside atmosphere and allowing the contents to boil safely.

Once the pressure vessel is closed the access key must be returned to the interlock valve in order for it to be closed and the vessel repressurised.

As with all Mistura interlocks and fittings, the interlock is machined from solid stainless steel, for strength and durability.

It has a polished finish which is easier to clean and more hygienic than comparable cast components.
