ValvXpress Automated Valve Package
Brand: ValvTechnologiesValvXpress® – 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.
ValvXpress® pre-engineered, automated packages are compact, robust and ready to ship.
Pre-engineered package includes:
- 1/2″ – 4” metal-seated V1-1 ball valve
- Socket weld and butt weld end connections
- A105, F22, F91 body materials
- 2500#-4500# pressure classes
- Valve operating conditions to 1400°F (760°C)
- High-cycle pneumatic rack and pinion actuator
- Hard anodized coating
- High-temperature Viton® seals
- High-cycle mounting hardware
- Limit switch with position indicator – 2-SPDT, quick set cam, IP67, NEMA 4/4X
- NAMUR solenoid – 110V/120V, 230V, 24VDC coils
- Filter/regulator with gauge
- Retainer prevents stem driving into ball
- Integral metal seat - With our patented HVOF RiTech® coating process, the integral seat in ValvTechnologies’ rotary operating valves are resistant from the attack of abrasive magnetite or ferrous oxides in the steam flow.
- 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
- 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.
- Live-loaded gland area - The V Series gland packing design features a four stud, live-loaded assembly designed for heavy industrial applications. The packing material is high purity Grafoil® surrounded by carbon fiber / Inconel anti-extrusion rings. The six Bellville springs (per stud) provide constant load pressure through extreme thermal shocks and prevent wear leaks in high cycle service.
- 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.
- Zero-leakage backpressure protected bi-directional sealing - This superior back pressure protected sealing capability comes standard with the V1-1 Series valve. ValvTechnologies’ standard design prevents the upstream load spring from collapsing in a reverse flow condition. The design protects the internals from damage after an upset condition and guarantees shutoff in the reverse direction.
- Zero-leakage shutoff - Shutoff is absolute zero-leakage, exceeding the requirements of ANSI/FCI 70-2, ANSI B16.34 and API 598.
