An all-electric, high-efficiency, cage-guide control valve system, the GVP-100 simplifies and enhances natural gas production and distribution operations. The GVP-100 operates using a solar panel and 12 VDC battery system, making it well suited for the natural gas market where low power consumption is critical.
The GVP-100's digital actuator employs a gear-reduced, low-power brushless motor to minimize power requirements. This design allows for the use of simple solar charging and storage battery systems, while reducing power source costs and replacing expensive electric actuators. The GVP-100's DSP-based digital driver boasts benefits such as self-diagnostics, remote monitoring and configuration. Plus, its efficient valve design minimizes flow restriction for maximum capacity.
The GVP-100 addresses maintenance and regulatory issues associated with traditional valve technology. The all-electric GVP-100 does not require gas for actuation, and as such, eliminates environmental and safety concerns derived from venting gas to the atmosphere.
The GVP-100's new, patented, pressurized stem seal technology provides improvement in the prevention of fugitive emissions as compared to standard valve packing systems. This results in savings for an operating facility to detect leaks and repair seals. The GVP-100 design relies on low friction sealing components that allow the valve to exceed the federal and state fugitive emissions standards over a much longer period of time than the traditional stem seal solution.
The GVP-100 is a fully integrated control valve, actuator and digital positioning system that only requires power and a setpoint signal for operation. This integrated configuration eliminates the need for third-party control valve assembly, including mounting of accessories such as: I/Ps, regulators, pneumatic positioners, let-down regulators, instrument tubing and fittings, external linkages and brackets common in pneumatic systems.
