The Alfa Laval Unique Single Seat Valves DN125 and DN 150 are versatile and reliable pneumatic single seat valves with a single contact surface between the plug and the seat to minimize the risk of contamination.
With a modular, hygienic design, the single seat valve meets the highest process demands in terms of hygiene and safety. Few moving parts ensuring high reliability and low maintenance costs. A wide range of optional features enables customization to specific process requirements.
Versatile and reliable single seat valve
Alfa Laval single seat valves (SSV) are robust and reliable pneumatic seat valves that are supremely reliable and versatile.
Modularity provides cost-effective and nearly endless possibilities for purpose-built seat valves bodies, plugs and actuators to meet virtually any requirement.
Superior valve process safety
The Unique SSV range is built on proven modular platform used on more than a million valves in service worldwide. Pressed from a single stainless steel disc, the valve body is extremely strong and durable, thus ensuring production safety. The enhanced performance of the actuator makes operation safer and more efficient.
Greater valve durability
To ensure high selling quality, the Unique SSV range provides long service life, reduced product loss, greater product safety and more processing uptime. Few moving parts reduce service requirements and inventory costs. More effective CIP procedures with reduced cleaning cycles and, subsequently, the reduced use of cleaning fluids, water and utilities also contribute to the Unique SSV’s low total cost of ownership.
Standard Design
The Alfa Laval Unique SSV DN125 and DN150 range is available in one- or two-body configuration, with easy-to-configure valve bodies, plugs, actuator and clamp rings. The valve can be configured as a shutoff valve with two or three working ports and as a changeover valve with up to four ports.
To ensure flexibility, the valve seat that sits between the two bodies in the changeover version is provided for assembly. The valve seals are optimized for durability. The actuator is connected to the valve body using a yoke, and all components are assembled with clamp rings.
To facilitate installation the valve is partially assembled when delivered. The standard valve has weld ends; it is also available with optional fittings. Due to the valve size and weight, the use of support equipment is recommended when handling and installing the valve (*not provided by Alfa Laval, refer instruction manual*)
The valve can also be fitted with the Alfa Laval ThinkTop V50 and V70 for sensing and control of the valve. Using the Alfa Laval Anytime configurator, it is easy to customize to meet virtually any process requirement.
Working Principle
The Alfa Laval Unique SSV is operated by means of compressed air from a remote location. The actuator smooths operation and protects process lines again pressure peaks. The valve can be controlled using an Alfa Laval ThinkTop®.
