Description
The K-022 Air & Vacuum Valve discharges air during the filling or charging of the system, and admits air to the system during system drainage.

The valve is specially designed to operate with liquids carrying solid particles.

The valve's unique design guarantees complete separation of the liquid from the sealing mechanism and provides optimum work conditions.

Main Features
• Working pressure range: 3- 360 psi. Testing Pressure: 580 psi.
• Working Temperature: 140° f
• Maximum working temperature for short time period: 1940° f.
• The valve's unique design prevents any contact between liquids and the sealing mechanism by creating an air gap at the top of the valve. This air gap is guaranteed even under extreme conditions.

Those features are achieved by:
• The conical body shape designed to maintain the maximum distance between the liquid and the sealing mechanism; so as to obtain minimum body length.
• The valve design and float mechanism are less sensitive to pressure differentials than a direct float seal. It has a comparably large orifice for a wide pressure range (up to 360 psi).
• Funnel-shaped lower body is designed to ensure that residue solid matter will sink to the system and be carried away and will not remain in the valve.
• Flushing is possible while the valve is under pressure, by opening the ball valve in the valve's lower part.
• Body made of Stainless Steel or fabricated Steel DIN ST.37.

Valve Selection
• These valves are manufactures with flanged ends to meet ASA 150 standard or any requested standard. The 2” valve is also available with NPT male threads.
• These valves are available with body of stainless steel or steel DIN ST.37 FBE coated.

Ordering
Upon ordering, please specify: model, size, working pressure, threads/flanges standard and type of liquid.
