Series/Model Information

The Parker VR7 Series is a relief valve that’s designed to vent excess pressure from a regulator should a minor seat leak occur. This valve serves as a highly economical way of protecting the regulator and outlet pressure gauge and is not intended for applications where repeated or frequent venting is required. It is available in stainless steel or brass. The VR7 Series is suitable for use with both inert and corrosive gases. It is available with variety of connections to ensure compatibility with a broad range of pressure regulators. Seals are available in FKM or FFKM for compatibility with different process media and operating temperature ranges. Pressure ranges of the VR7 Series relief valve are also adjustable to meet the unique requirements of the operation. In situations where gas cannot be vented to atmosphere, the outlet of the relief valve can be connected to an external tubing line.
