HG47 Series Gauge/Block Valves
A roddable, hard seated orifice valve that overcomes the drawbacks of conventional valve designs. Ideal for use on high temperature, viscous services, the HG47 provides full port, unrestricted flow. The HG47 features an OS&Y bolted bonnet with weld or threaded connections. The accessible hard seat insert and non-rotating tip (NRT) stem are machined for precision fit, yet field-replaceable to allow for long service life.
- High Temperature, Full Ported - Use on viscous services up to 850°F. Universal 1/2" outlets allow rodding tool positioning without the removal of tubing or instrument.
- Easy Maintenance for Long Service Life - Easy to remove non-rotating stem tip allows for easier maintenance than found with conventional valve designs.
- reduce Installation Time - Threads directly into the orifice flange for quick, compact and simple installation.
- Reduce Potential Leakage - Reduces the number of threaded connections in half resulting in fewer potential leak points as compared to conventional root valve assemblies.
