Four-Way Valves
Repeatable Shutoff for Critical Applications.
ValvTechnologies’ metal seated three and four-way valves are designed for the most severe applications where flow diversion is combined with the need for repeatable tight shut-off. Both three and four-way valves are available in ‘T’ and ‘L’ configurations and in multiple combinations of body materials, trims and end connections.
Temperature-resistant up to 1400°F (760°C), ValvTechnologies’ metal-seated three and four-way valves are precisely right for your most severe applications. Use them where solids, high-temperatures and high-velocities demand proven shutoff reliability and effective flow diversion.

Technical Data
AbrasoCheck® Slurry Check Valves
Low Wear, High Isolation
The AbrasoCheck® slurry swing type check valve is designed specifically for PD slurry pump discharge isolation and allows in-line maintenance. The valve was based upon the existing design as used for more than 30 years at an iron concentrate pumping station. Currently the valve is in use in China, India and Brazil on slurry pipeline pump stations.
The AbrasoCheck® slurry check valve will operate on pump shutdown and start-up.
The purpose of the double acting pneumatic cylinder is to assist the disc into the closed position and to hold the disc in that position, during pump shutdown and also to hold the valve open during normal operations.
The valve is supplied with a double acting pneumatic cylinder that is fixed to the valve body and connected to the valve stem. Once the valve is fully open then the cylinder can be energized to hold the flapper in the fully open position and out of the path of the slurry flow.
The combination of ValvTechnologies’ AbrasoCheck® slurry check valve and AbrasoTech® slurry ball valve provides zero-leakage isolation for maintenance of positive displacement pumps.

Case Study: Molecular Sieve Switching Valve Superior Design
Product: V1-4
Location: Kazakhstan
Plant type: Oil & gas
Background: Facing hundreds of millions of dollars in production losses annually, a major global oil company placed a multi-million dollar order with ValvTechnologies for molecular sieve switching valves to replace their existing rising stem ball valves.
Requirement: The issues in this service, which handles gas with an H2S content of over 20%, included leakage to atmosphere, unreliable operation, mechanical breakdowns and unscheduled shutdowns. In addition to the safety and environmental concerns, the client faced threats to the integrity of the downstream equipment. The initial response to these challenges included the planning of a full parallel dehydration facility to cope with the ongoing concerns with the legacy equipment.
Solution: For over a decade ValvTechnologies has provided molecular sieve switching valves in similar applications throughout the world. This proven track record gave our customer the confidence to engage ValvTechnologies in a conversation regarding their challenges. Upon careful review of the application and in consultation with ValvTechnologies’ senior Engineering staff, the selection was made to employ ValvTechnologies’ seat supported design technology. The selected materials included Inconel 825 for the valve body components and Inconel 718 for the internals.
The supply, which included full pneumatic automation of all the valves, was completed in less than 20 weeks – in time for a scheduled shutdown in 2013. ValvTechnologies assisted with the site testing, installation, commissioning and startup.
The operational performance of the valves since startup has exceeded the client’s expectations. With this experience, the client felt confident to cancel the scheduled parallel installation project, which saved them hundreds of millions of dollars.
ValvTechnologies assists its clients in meeting their goals regarding safety, the environment, cash flow and asset protection.

EcoPack® Fugitive Emissions Packing Solution

Technical Data
ValvTechnologies’ EcoPack® Packing Solution for the Reduction of Fugitive Emissions.
Reducing fugitive emissions is a leading concern in the fight against climate change. The EPA estimates that the production segment of the oil and natural gas industry is responsible for 45% of total methane emissions. In 2015, the first-ever plan to regulate emissions from this industry was launched: because valve leakage is responsible for more than 50% of total fugitive emissions, valves have been a considerable focus in the effort to reduce fugitive emissions.
ValvTechnologies’ is leading the charge in the reduction of fugitive emissions with the development of the EcoPack®: a superior stem packing solution for high-cycle, fast acting valves that meets stringent fugitive emissions requirements.
ValvTechnologies NexTech® pulsejet valve with EcoPack® was recently tested by an independent agency that verified the solution not only met but exceeded endurance testing standard performed 500,000 cycles while retaining a maximum leakage rate equivalent to ISO 15848-1 2006 Class BH for the entirety of the test.
Typical stem sealing technology requires packing adjustment. With high-cycle valves, these adjustments would have to occur very often, causing disruptions in plant operation, safety concerns and non-compliance with tightening emissions regulations. With the EcoPack® solution, lab tested results show the seal is capable of 500,000+ cycles with the stem packing requiring zero maintenance or adjustment. This solution is perfect for customers requiring a quickly-rotating valve that completes many cycles annually (i.e. 250,000 per year or more) and must also meet fugitive emissions requirements.
Features:
- Meets ISO-15848-1 testing requirements for fugitive emissions certification in process
- Packing requires zero adjustment or maintenance
- Capable of 500,000+ cycles
- Durable packing solution for extremely fast cycle speeds of less than 0.5 seconds
Benefits:
- Longer intervals of plant operation between maintenance schedules
- Safer plant operation due to less exposure of plant personnel to valves requiring packing adjustment
- Longer valve seal life
- Reduced emissions to comply with EPA fugitive emissions requirements

- Simplified, Robust Design: Opposite chambers in the actuator are connected by pressure equalizing passages in the upper and lower head.
- Simplified, Robust Design: The actuator produces well-balanced torque as hydraulic force pushes both of the rotary vanes away from the shoes
