The LPHF Series Assist Gas Regulators deliver high pressure and high flow of inert gases. The key to the performance of this regulator is the servo-dome load technology. The servo-dome load feature allows the regulator to supply high flow rates with straight line pressure regulation. The LPHF series is constructed of brass barstock, with PTFE seats and seals. The maximum inlet pressure is 3000 psi.

Features

• 250, 500 & 1000 PSI delivery pressure
• Fast on/off response, even at high flow
• 3000 psi inlet pressure 
• Tamper proof, self-reseating internal safety valve 
• One piece encapsulated seat design with 10 micron filtration
• 1/2” NPT female outlet
• Conforms to CGA E-4 standard for gas pressure regulators

*Note: where CGA is replaced by the actual CGA number. Some CGA limitations may apply. (NI) for 1/2" FNPT inlet

	Mounting Options
	LPHF-WMBR Mounting Bracket for Assist Gas Regulators Mounting Nut is also needed (see below). The regulator knob will have to be removed in order to mount on this bracket.
	LPHF-PMN Mounting Nut This nut can be used either with the above bracket or for mounting in a panel.
	53 Series Protocol Station This brass manifold is designed to provide a safe, reliable way of wall-mounting a cylinder regulator. Manifolds are provided a durable stainless steel bracket, stainless steel flex hose (3 ft std.), and a CGA connection with integral check valve.
