Pneumatic Relays and Volume Boosters Specifications

Help with Pneumatic Relays and Volume Boosters specifications:

Type

	Your choices are...
	Volume Booster		Volume boosters provide a large change to input signals and deliver a high volume of control flow.  They are used to control stroking speeds of valves and actuators.
	Air Lock Relay		Air lock relays are used for fail-in-place applications when an air supply drops below acceptable pressure levels. Its position is maintained by capturing air pressure inside the controlled device.
	Bias Relay		A bias relay reproduces a signal pressure plus-or-minus a preset bias.
	Electric / Pneumatic Relay		Electrically-operated pneumatic switches.
	Ratio Relay		Ratio relays are pneumatic relays that produce a modulating pressure output that is proportional in a fixed ratio to input.
	Reversing Relay		Reversing Relays provide an output that equals a manually preset spring load minus a variable signal pressure.
	Snap Acting Relay		Snap acting relays are accurate differential relays that snap open when the supply pressure is greater than or equal to the set point.
	Switching Relay		Switching relays are used to block, divert, or bleed pneumatic air lines.
	Other		Other unlisted or specialized air relays or boosters.

Performance

	Output Pressure		The output pressure is a signal or boosted pressure.
	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.
	Set Point Pressure		The set point pressure refers to the range that the relay can be set to actuate.
	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.
	Maximum Pressure		Maximum operating pressure.
	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.
	Flow Capacity		Flow rate
	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.
	Port Size		This refers to the size of the air / gas connection.
	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.

Features

	Body Material
	Your choices are...
	Aluminum		Aluminum is a bluish, silver-white, malleable, ductile, light, trivalent, metallic element that has good electrical and thermal conductivity, high reflectivity, and resistance to oxidation.
	Stainless Steel		Stainless steel is chemical and corrosion resistant and can have relatively high-pressure ratings.
	Other		Other unlisted or specialized material.
	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.
