REGIONS SUPPLY BUYING GUIDE

Product details & buying advice

Choose the valve around the transfer or shutoff duty, paying attention to the flow path, sealing materials and how the handle will be operated.

Product type Globe, angle and hose-end shutoff valves
Part / SKU 7551P

What to check before ordering

  • Verify the liquid or vapor application, connections, material compatibility and permitted working pressure.
  • Check the marked flow direction and mounting requirements, with enough access to operate the handle.
  • Have qualified personnel install the valve and complete the required system checks.

Service reminder: Read the model’s actual LP gas rating. A WOG marking alone does not establish suitability for every gas application.

Have gas-system installation and service completed by qualified personnel. Use the current instructions for the exact model and the requirements that apply at the installation location.

Overview

**Engineered Controls 7551P — 3/4" MNPT x 1/2" FNPT LP Gas Liquid Transfer Angle Valve

For Bulk Storage Tanks • Flange Seal Stem • Leak-Proof Operation**The Engineered Controls 7551P liquid transfer angle valve is designed specifically for the liquid withdrawal and vapor service of LP-Gas from bulk storage containers. When used with a Chek-Lok or compatible installation, this valve provides high-capacity, leak-free performance for propane transfer and vapor equalization applications.

Built with a flange seal stem design, the 7551P eliminates the need for packing adjustment—reducing maintenance and ensuring long-term leak-proof operation. Large internal flow passages reduce pressure drop and prevent cavitation, increasing reliability and transfer capacity.

This model includes a plugged 1/4" NPT boss for installing a hydrostatic relief valve or vent valve, and a resilient swivel seat disc that delivers longer life and positive shutoff.
