Metal Seated Ball Valves
Longer service life means reliable, maintenance-free operation and a four year leakage warranty for power industry applications. This is just the start of what you get with ValvTechnologies’ seat-supported severe service metal-seated ball valves.
The V Series’ proven seat design provides improved performance, far beyond the capability of linear operated valves – which feature obstructed and torturous flow paths. V Series valves are engineered to be leak-free, position-seated, maximizing flow and reducing the overall cost of ownership. ValvTechnologies’ design and construction delivers the extra safety margin so crucial to maintaining productivity.
Decrease unscheduled downtime and possible production losses with ValvTechnologies’ coker valves.
The delayed coker process is a batch process, one of the most hostile environments in the refinery due to the abrasive and erosive properties of the coke by-product – and is crucial to a refinery’s profitability. Valves are cycled frequently and failure can lead to a complete shutdown of a unit, resulting in large process and financial costs. Optimizing valve life-cycle is critical to operational efficiency: ValvTechnologies has the best solutions to meet your coking requirements.
ValvTechnologies’ Xactrol® severe service control valves are engineered for applications where minimum flow and relatively high differential pressures are required. They provide “exact” flow control solution every time, from minimum or normal control to full rangeability across a wide range of pressure drops and conditions.
Pulse Jet Valves
ValvTechnologies’ PulseJet valve is a fast-acting, high-cycle fugitive emissions valve designed to send a pulse of gas through a pipeline system. A trunnion-mounted ball valve, capable of 90° or 180° rotation in speeds as low as 0.5 seconds or faster, this fast actuation speed is what creates the gas “pulse” through the pipeline system. PulseJet systems can be used to clean system filters, spray chemicals in an injection type system, or pulse debris/media through a pipeline to prevent clogging.
Electronic Relief Valve
Consider the safety rating, productivity value and cost savings of electronic relief valves – the relief valve whose standard blowdown and set pressure is accurate to 1/10% of 1 psi. ValvTechnologies’ ERV is the perfect combination of zero-leakage isolation valve plus the electronic controls needed to monitor and regulate system pressures in a safety valve environment and within ASME Code Section I “V” Stamp requirements where critical over-pressure protection is paramount. ValvTechnologies’ ERV is the benchmark.
Acid Injection Valve
No-Leak Safety for Mineral Processing
To maintain cost-effective operation of pressure acid leaching, there is the ValvTechnologies’ severe service acid injection ball valve. A unique product, it was created and designed for the isolation and emergency shutdown of high-pressure acid leaching (HPAL) autoclave acid injection systems. This valve uses ceramic seats, coatings, and exotic metals to provide plant safety in the harshest of process conditions. Its operating benefits continue to be demonstrated every day in mining facilities throughout the world.
The acid injection valve product line is used in the mining industry for high-pressure acid leaching HPAL of nickel, using autoclave technology. The acid injection valve product is an invention of ValvTechnologies, in response to a need for a special application valve, as a result of a hazard and operability study which was carried out for the Bulong Nickel Project in 1997.
ValvTechnologies / DFT® Nuclear Check Valves.
ValvTechnologies is an exclusive distributor of in-line check valves for nuclear applications and licensed manufacturer of ASME III and safety-related check valves.
Designed to prevent “water hammer”, the spring-assisted, in-line design featured in all DFT® check valves ensures that as the forward flow in a pipeline decreases, the disc begins moving closer to the seat. By the time the flow stops, the disc is closed against the seat, preventing flow reversal. This prevents the valve from slamming closed, causing “water hammer” and the resultant noise and damage to piping systems.
Trunnion Metal Seated Ball Valves
The trunnion valve technology platform provides a unique combination of upstream seating seat principle, resistance to abrasive erosion, long lifetime, and availability in a wide temperature range. Designed to meet stringent emission requirements and provide long life in abrasive and erosive conditions, the NexTech®, TrunTech®, and PulseJet valves provide high-performance solutions for tough, high cycling applications.
Parallel Slide Gate Valves
IsoTech®, ValvTechnologies’ parallel slide gate (PSG) seat-protected valves, are the culmination of years of practical design enhancements and eliminating the limitations of typically accepted norms in gate valve design. Proven precisely right for steam and feed water isolation applications, IsoTech® valves offer our rigorous four-year, zero-leakage warranty for steam and water applications and low-cost maintainability.
The ValvTechnologies’ switch valves are designed for use in the delayed coker found in many integrated oil refineries. There are two drums in a delayed coker unit that work consecutively while in operation. When one drum is functioning, the other drum is being de-coked. The switching valve is required to direct hot feed to either drum A or drum B. The valve also has the bypass position to divert flow back to the fractionator for or during emergencies. The bypass has the same port dimension as the main drum feed lines. The control package also has the capability of providing multiple intermediate positions to provide the capability to warm the new drum while slowly reducing feed to the live drum. The switch valve is the most critical valve in the unit.
With the largest installed base of any metal seated ball valve manufacture in slurry service, ValvTechnologies understands what is required in difficult abrasive applications. ValvTechnologies’ slurry products have been designed based upon our 30 years of experience in the mining industry. Our integral seat design, zero-leakage testing requirements, and in-house coating capabilities have become the standard for long valve service life and reduced downtime in critical slurry applications where the valve cost is only a small fraction of the overall cost of downtime caused by a valve failure.
Automated Valve Package
ValvXpress® automated packages are the perfect solutions for customers who demand quick delivery of a zero-leakage automated valve solution for severe service water and steam applications. The package includes the superior quality of the V1-1 valve and ValvTechnologies’ actuator, backed with the best four-year guarantee in the industry.
Safest to Service.
Improve protection and isolate large equipment areas safely by specifying ValvTechnologies’ valves with double block-and- bleed capability. The proven-in-the-field ValvTechnologies “package approach” lowers installation costs – and saves time – compared to individual component assembly. A bi-directional upstream seat system, plus a bleed connection with a standard isolation valve, allows superior flexibility in use, as well as smooth, low-torque operation. Customers save on wear and tear, improve valve service life, and maximize effective in-line performance.
