1. Integral metal seat. With our proprietary HVOF RiTech® coating technology, the integral seat in ValvTechnologies’ valves is resistant to the attack of abrasive magnetite and ferrous oxides that may be seen in the steam flow.
2. Body seal ring. ValvTechnologies employs a field proven seal ring technology to ensure sealing under all operating conditions, up to 1400°F. The body seal ring is loaded at a pressure higher than 20,000 psi. In addition, valves sized three inch and above contain a secondary Grafoil seal to further guarantee reliability
3. Patented coating process. The sealing surfaces are overlaid with tungsten or chromium carbide using our exclusive HVOF RiTech® process. These surfaces have a hardness of 68 – 72 Rc to allow long periods of operation in the most severe conditions.
4. Live-loaded gland area. The V Series’ sealing design features a four stud, live-loaded assembly designed for heavy industrial applications. The sealing material is high purity Grafoil® surrounded by stainless steel wire mesh anti-extrusion rings. The six Belleville® springs (per stud) provide constant load pressure through extreme thermal shocks and prevent wear leaks in high-cycle service.
5. Blow-out proof stem design utilizes a one piece, hard-faced, blow-out proof stem that is inserted through the inside of the body cavity eliminating the possibility of blow-out through the gland area.

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.
