Product Name Notes
A high-performance externally air-piloted pressure-reducing valve, the GP-2000K-1/GP-2000K-3/GP-20000K-6 is an ideal choice when set-point changes are frequent and access to the PRV is difficult. The valve comes totally assembled and...
An industrial-grade valve for water systems, the GD-24 is lightweight, compact and economical. The valve comes with screwed connections and will mount in any position. It requires no external sensing...
The GD-10/10F is a lightweight direct-acting diaphragm valve used primarily for pneumatic tool air supply and non-hazardous gas regulation. Screwed connections make it easy to support in position without external...
The GD-200/200H valves offer high capacity and highly accurate control, with a large, cupped diaphragm for a long stroke. Compact and rugged, the GD-200’s composition valve and bronze metal seat...
The GD-2000K is an ideal choice when set-point changes are frequent, access to the valve is difficult and steam quality is poor. The GD-2000K comes with either NPT or flanged...
The GD-6N and GD-6 are compact, direct-acting diaphragm valves ideal for low-flow applications, including laundry/dry-cleaning equipment, hospital equipment, tire/plastic molds and food processing. Lightweight and compact, the valves require no...
The GP-1000 Series valves are pilot-controlled for accurate regulation of pressure under widely ranging flow. The internal-pilot design eliminates external components and piping. Internally piloted GP Series valves are capable...
The GP-2000 is a high-performance, externally piloted reducing valve for large-capacity requirements. Typical use is on intermittent service, including applications such as heat exchangers, steam coils, rotating dryers, process equipment...
The GP-2000L is a high-performance, externally piloted reducing valve for large-capacity and low inlet pressure requirements. The GP-2000L is reliable and accurate (+/-1% of pressure set point from 5% to...
