Ball Valves

Less fugitive emissions up to 450°C (842°F)
and pressures up to 420 bar (6,092 psi)

The ultimate facts about

Instrumentation Ball Valves

Instrumentation Ball Valves are the easiest and most direct way to realize a safe & accurate measurement. Either used as single isolation valve directly connected to the measurement device or as a part in a Close-Coupled Instrumentation Hardware Kit.

Application fields

AS-Schneider’s Instrumentation Ball Valves are very robust and especially designed for severe services within the chemical and petrochemical process industry. They can be used either as a single piece application or as a part in an advanced Close-Coupled Instrumentation Hardware. For environmental protection, the end connector and valve body are full penetration welded.

The metal seated series can be used in extreme operating conditions with temperatures up to
450°C (842°F) and pressures up to 420 bar (6,092 psi).

Benefits of
Instrumentation Ball Valves

All established connections types such as socket & butt welds, threads, I-flanges and ANSI flanges are available. In order to reduce emissions, all connection types are fully welded to the body.

Special services are calling for special materials of the housing and sealing parts. AS-Schneider offer Instrumentation Ball Valves in a wide variety of materials. Forged carbon or stainless steel bodies, bar stock alloys, coated balls and different soft seats or gasket materials are standardized.

The fully welded bodies in combination with an anti-blowout stem, anti-static design, fire safe approval and a lockable handle are as standard features and ensure safe operation at all times.

All items are produced in-house, modifications are no issue! No matter if an extended or oversized inlet is required or if the body should be designed as a multi-port with various outlets.

The design and material of the parts in use are optimized to ensure smooth and easily operation.

Design Highlight

(metal Seated)

Conventional Ball Valve Design

The forces required to maintain the tightness are stressing all components including the ball and seats. The operating torque is thus very high.

'Dissolution' Ball Valve Design

The required force to maintain the tightness between ball seat and valve body is only directed to the corresponding graphite seal rings. The ball is spring-loaded to ensure a defined, low minimum pressure off the ball onto the ball seat. That results in a smooth operation.

With the 'Dissolution' Ball Valve Design, AS-Schneider has introduced an innovative solution. This patented design offers an optimum distribution of forces and loads in the valve. The ball valve can be operated at low torque, even under extreme conditions.
