Air Pressure Regulators Specifications

Regulator Type


	Regulator
	Your choices are...
	Regulator (general)		Regulators maintain a constant outlet pressure.
	Back Pressure Regulators		Back pressure regulators control upstream (inlet) pressure. They function similarly to relief valves.
	Change Over Regulators		Change over regulators are combination valves and pressure regulators, fitted to a multiple-cylinder assembly that will automatically change over from a cylinder in use to a reserve cylinder at a predetermined pressure.
	Differential / Bias Regulators		Differential pressure regulators, or bias pressure regulators, maintain constant differential pressure between a reference pressure and the pressure of the controlled fluid.
	Filter, Regulator, Lubricator Assembly (FRL)		Filter, regulator, lubricators (FRL) are pre-packaged or modular assemblies of common configurations of air filters, regulators, lubricators and gauges.
	Point of Use Regulators		Point of use regulators are installed directly into fluid lines. They are single stage regulators that are used to provide point-of-use pressure monitoring and control. Point of use regulators are often referred to as line regulators.
	Pressure Reducing Regulators		Pressure-reducing regulators are used to provide a sub-circuit with a supply of fluid at a pressure that is less than the pressure in the main circuit.
	Two Stage Regulators		Two-stage gas regulators reduce cylinder pressure in two steps and should be used when constant delivery pressure is needed without periodic adjustment.
	Vacuum / Absolute Pressure Regulators		Vacuum or absolute pressure regulators control fluid at low positive pressures or below atmospheric pressure (absolute pressure).
	Other		Other unlisted, specialized, or proprietary regulators.

	Media Temperature		Maximum temperature of media the valve is designed to accommodate.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	Actuation
	Your choices are...
	Manual / Hand		The valve is actuated (opened or closed) via a hand operated wheel or crank.
	Mechanical Device		A mechanical device such as a float or cam activates the valve. This does not include powered actuators.
	Electric		An electric actuator activates the valve.
	Electro-hydraulic		A servo valve that produces hydraulic control in response to an electrical signal input.
	Electro-pneumatic		A servo valve that produces pneumatic control in response to an electrical signal input.
	Pilot Operated		A pilot valve activates the valve.
	Pneumatic		The valve is activated by a pneumatic actuator or cylinder to open and close valve.
	Thermally Actuated		The valve is activated by a change in temperature in the handled media. Typically, temperature and pressure relief occurs once a preset temperature is reached.
	Other		Other unlisted, specialized, or proprietary actuation method.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Features



	Your choices are...
	Stack Mounted		The valve is constructed in a modular format, so that it can be assembled to create a valve block. This type of valve is also referred to as a sandwich or modular valve.
	Cartridge / Manifold Valves		Cartridge valves are directional control valves that are inserted into manifolds to provide a cost effective compact system design.
	Severe Service Rated		The valve is designated by manufacturer as being suitable for severe service applications where there are continuing operational, maintenance or reliability issues with a given application.
	Precision Control		The valve has the ability to accurately control the flow or pressure.
	Lockout / Tamper Proof		The valve has a device to prevent unauthorized use.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
