Master Flo - Choke Insert Module Retrieval
The HRV design enables efficient retrieval of the choke insert module, including the canister, bonnet-clamp connector, and actuator. The canister, a crucial part of the valve trim and seals, protects the valve body during servicing.
The HRV valves feature Master Flo’s metal-to-metal sealing technology, providing reliable performance in critical sealing areas.
Bonnet Seal: Master Flo’s bonnet seal, a double-tapered metal seal, ensures robust sealing between the bonnet and body of the HRV valve. When engaged, it provides a strong initial mechanical load, which is further pressure-energized in operation. This seal also facilitates the disengagement process, allowing easy retrieval of the insert.
Bean Seal: The bean seal in the HRV valve is a single-lip metal seal designed for effective sealing between the choke insert assembly and the valve body. Energized by the clamp connector during assembly, it offers dependable performance, further enhanced by fluid pressure in service.
Stem Seal: The HRV valve’s stem seal is a single-lip metal seal, pressure-energized to ensure reliable sealing between the valve bonnet and stem. It includes a protective stem wiper to prevent mechanical damage, exemplifying Master Flo’s commitment to durable and efficient design.
