With an increase in the globe valve size, the power required to operate increases. In an open position, the valve stem rises and popped out at the top.Īn example of a non positive valve would be an air operated diaphram valve (typically used as a regulator). The motor operated valves (mov) is an important element of the plant and pipe system. Knife valve, similar to a gate valve, but usually more compact. Source: The motor operated valves (mov) is an important element of the plant and pipe system. In this control system, when process variable. Source: In most cases, valves fall into one of three categories: Valves are technically fittings, but are usually discussed as a separate category. These valves are generally large and are used for different applications such as pump discharge, etc. An example of a non positive valve would be an air operated diaphram valve (typically used as a regulator). In other words, the on/off valve is the fluid equivalent of an electrical switch. This control element does not operate at any intermediate position, i.e. In most cases, valves fall into one of three categories: It either allows the fluid to pass or block through it. Solenoid Valves Introduction from An example of a non positive valve would be an air operated diaphram valve (typically used as a regulator). The control valves operated by motor are often called on / off valves since the motors serve to open or completely close the valves in the pipes. A valve that doesnt have positive shutoff can leak by and allow fuel to feed a fire. The Type-870 Miniature Potable Water Pressure Regulator weighs 4.0 oz. A wide temperature range of 0º to 150º F (-18º to 60º C). Two gauge ports and an optional reversible mounting bracket allow front or back mounting. Maximum supply pressure is 150 psig (10 BAR). The Type-870 Potable Water Pressure Regulator is available in 1/8” or 1/4″ NPT & BSP porting. Diaphragm and O-ring are made of food grade nitrile/nylon and the valve plug is made of lead-free brass and food grade nitrile.

The bonnet and valve seat are FDA approved acetal. The body is made of NSF electrodeposited chromium plated zinc. A molded rubber supply valve provides accurate regulation and helps prevent leakage. Applications include equipment manufacturers in the foodservice, dental, medical, and agricultural industries.ĬontrolAir’s Type-870 uses a highly sensitive diaphragm-operated design which delivers accurate downstream pressure by eliminating the problems caused by sticking in piston designs utilized by competitors. The Type-870 Miniature Potable Water Pressure Regulator is ideal for any application that calls for accurately maintained output potable water pressure control. Elastomers in the Type-870 are food grade. Materials in contact with water are approved by National Sanitation Foundation (NSF) or the Food and Drug Administration (FDA) for use in potable water systems. The Type-870 is designed for OEM equipment used in potable (drinkable) water and food contact systems. The new Type-870 is an addition to ControlAir’s Type 850/860 Miniature Air and Water Series.

ControlAir Inc., a manufacturer of precision pneumatic and electro-pneumatic control products, announced they are expanding their product offering to include a new miniature potable water pressure regulator.
