VALVES

The Squibb Taylor P327D is a pneumatic actuator used to operate an Emergency Shutoff Valve (ESV), such as the Fisher N550 or N551 "Snappy Joe". It is designed for remote, air-powered operation, specifically for closure, in applications involving hazardous materials like LP-gas or anhydrous ammonia. 

The Fisher N551-10 Snappy Joe Emergency Shutoff Valve for Anhydrous Ammonia (NH3) is a valve with a 1-1/4 inch NPT connection, designed for high flow with a 400 psi maximum inlet pressure. It features a ductile iron body and a fusible element that melts at approximately 212°F (100°C) to automatically shut off flow during a hose rupture. 

The Fisher N551-16 Snappy Joe Emergency Shutoff Valve for Anhydrous Ammonia (NH3) is a valve with a 2 inch NPT connection, designed for high flow with a 400 psi maximum inlet pressure. It features a ductile iron body and a fusible element that melts at approximately 212°F (100°C) to automatically shut off flow during a hose rupture.
