Compact Wafer Style Ball Valve
Compact Wafer Style Ball Valve
The Compact Wafer Style Ball Valve provides on/off flow control in industrial piping systems where installation space and valve dimensions are important. Installed between compatible mating flanges, it is suitable for applications requiring a compact valve configuration.
Product Overview
Compact Body Design: Reduces the space required for valve installation compared with selected conventional flanged designs.
Quarter-Turn Operation: Uses a 90-degree rotation to open or close the flow passage.
Material Options: Body, ball, stem, and seat materials can be selected according to the process medium and operating conditions.
Actuation Options: Manual operation or pneumatic/electric actuation, subject to the available valve configuration.

Frequently Asked Questions
Q: What is the main advantage of a compact wafer style ball valve?
A: Its compact body can reduce installation space compared with selected conventional flanged valve designs.
Q: Can it fit between ASME or EN flanges?
A: Compatibility depends on the specific valve dimensions, flange standard, pressure rating, and face configuration. Confirm these details before ordering.
Q: Can pneumatic or electric actuators be installed?
A: Actuator compatibility depends on the valve stem design, mounting interface, and operating torque. Confirm the required configuration with the supplier.
Q: How do I choose the seat material?
A: Consider the fluid composition, chemical compatibility, operating temperature, pressure, and cycling frequency.
Q: What documents can be supplied?
A: Material certificates, pressure-test reports, dimensional inspection records, and conformity documents may be available depending on the model and order requirements. Confirm the required documentation during quotation.
