A pilot valve 2012-01-10
A generic valve is known from EP-A-0 893 607. This known valve is a magnetically operated drain valve in which, between a load pressure port (P) and a drain port (T) in the lifting module of a forklift, a seat closing element is assigned to the main valve seat and in the closing direction can be pre
Control valves with pneumatic devices 2012-01-06
Many pneumatic devices require control valves that are cheap, reliable and rugged. Heretofore it has been proposed to employ a three-way ball valve of the type comprising a valve body having two axially spaced ports, a valve seat associated with each of those ports, a third port located between the
The valve mechanism 2012-01-05
The control outlet can be located adjacent either the supply inlet or the supply outlet. The control outlet can include a control passage having an inner opening communicating with an outer opening near the exterior of the demand valve body. The outer opening of the control passage can be adapted fo
Valve for controlling the pressure 2012-01-04
The manufacture of urethane foams, for example, involves supplying two or more reactive components in accurately metered proportions to a mixing device from whence the mixed components are deposited in a suitable mold wherein the mixture reacts to produce the polyurethane foam. These components are
A control valve for controlling the flow of fluid 2011-12-31
According to the invention there is provided a control valve of the pilot-operated kind comprising a valve body which includes a main valve seat; a movable main valve cooperating with the main valve seat to open and close the valve; a piston carrying the main valve member; a control chamber behind t
The structural length of the valve 2011-12-30
The valve according to the invention as proposed here opens in such a way that the valve cone emerges from the valve housing. On the one hand, this reduces the structural length of the valve, and at the same time it also offers the possibility of enlarging the flow diameter in the region of the valv
A valve of the type usable with an internal combustion engine 2011-12-29
As is well known, valves for internal combustion engines are opened and closed in a predetermined sequence to control the movement of gases to and from the cylinders with the speed of movement of the valves being proportional to engine speed. Typically, valves of this type are biased by a spring tow
A movable valve body 2011-12-27
In accordance with a further aspect of the invention it can be provided that the valve body is adapted to be actuable by a piston which can be acted upon at both sides, wherein the piston is arranged in a piston housing and at least one chamber can be acted upon with a variable pressure by way of a
