Installation notes
Protect sealing components during installation of welded ends
When installing J4 Series valves with socket-weld or butt-weld connections, protect the ball, seats and valve body sealing areas from welding heat to prevent sealing component deformation or failure that could result in leakage.
Depressurize and drain the medium before disassembly or maintenance
Before disassembling or maintaining the J4 Series three-piece valve body, isolate the pipeline, release residual pressure in the valve body cavity and drain the medium to prevent trapped medium from being discharged when the body connection components are loosened and causing personal injury.
FAQ
What size, pressure rating and piping connection options are available for the Neles Easyflow J4 Series?
The J4 Series is available in nominal sizes DN15-DN50 (NPS 1/2-2), with a Class 800 pressure rating. Full-bore and reduced-bore versions are available, with threaded, socket-weld and butt-weld connections. Threaded and socket-weld ends comply with ASME B16.11, while face-to-face dimensions follow the manufacturer's standard. During selection, verify the pipeline size, bore configuration, connection type and installation dimensions.
How does the Neles Easyflow J4 Series combine tight shutoff with repeatable operation and control?
The J4 Series uses a low-torque seat design to provide bubble-tight shutoff during pressure and temperature cycles. The close drive fit between the stem and ball supports precise and repeatable shutoff and control. Its leakage criterion is no visible leakage, and the valve is tested in accordance with API 598.
Can an actuator or manual operating mechanism be installed directly on the Neles Easyflow J4 Series?
The J4 Series features an ISO 5211-compliant mounting platform for direct installation of handles, gear operators, manual override mechanisms or actuators. It can also be equipped with Neles actuators, switches and controllers. A lockable handle is available when handle operation must be restricted.
What design features of the Neles Easyflow J4 Series reduce maintenance requirements and improve stem safety?
The J4 Series uses a robust three-piece valve body construction for easy maintenance. The spring-preloaded stem sealing design provides low maintenance requirements, extended cycle life and low emissions. An internally mounted blowout-proof stem design helps prevent stem ejection. Anti-static grounding is provided between the ball and stem and between the stem and valve body.
What optional configurations are available for the Neles Easyflow J4 Series when reduced valve cavity medium retention is required?
The J4 Series can be equipped with an optional valve cavity filler design to reduce medium retention in the valve cavity. This configuration may be considered for applications where residual medium in the valve cavity is a concern.
