Three key features combine to make the SV1 more durable, with less maintenance than competitive push-through slurry valves. Along with slicing through slurries more efficiently, these features prevent seat damage, which is a common issue with many push-through slurry valves. The angled-cut Guillotine Gate design slices through media the way that an angled knife would cleanly slice through a tomato, rather than simply pushing through and squishing the seats.
The slick plastic, ultra-high molecular weight (UHMW) polyethylene gate support liners within the SV1 guide the gate through the entire stroke, shielding the body of the valve from direct contact with the media while reducing downstream gate deflection and preventing the gate from cutting the seat. Seat protection is key in reducing downtime on slurry valves. Seat damage is a common issue with many push-through slurry valves, leading to a seat replacement or whole valve replacement to fix the problem.
The proprietary engineered polymer seats reduce friction and also increase seat life, particularly in high-solid slurries. The Fabri-Valve SV1’s resilient material requires no lubrication, which saves on maintenance costs. Even valves that claim to self-lubricate, as opposed to those that need to be manually lubricated, can create maintenance troubles because lubrication can trap particles, and gritty lubrication can eventually affect valve operation.
The SV1 is designed for easy installation and maintenance. The gate can be completely removed and replaced while the valve is under pressure, actuation can be changed in the field, and valves with manual operators or air cylinders have self-supporting yokes to provide valve orientation flexibility.
