TLDR
A cylindrical heat-generating member is disposed in a valve casing including a valve seat in a flow path connecting main ports, a valve member for opening and closing the valve seat, and a rod connecting the valve member and a piston as discussed by the authors.Abstract:
A cylindrical heat-generating member is disposed in a valve casing including a valve seat in a flow path connecting main ports, a valve member for opening and closing the valve seat, and a rod connecting the valve member and a piston. A first heater is mounted in the heat-generating member. The heat-generating member and a heat receiving member of the valve member are connected to each other by a heat-transfer member for expansion and contraction. As a result, the valve member is constantly heated through the heat-transfer member irrespective of its open/closed position. When the valve member is open, the heat receiving member comes in contact with the heat-generating member and the valve member is directly heated.read more

Vacuum regulating valve
Masao Kajitani,Kazuo Hiramatsu +1 more
TL;DR: In this article, the main controller in the valve control section outputs a signal for setting the opening of the valving member to a motor controller that controls the electric motor, and performs control to cause a pilot fluid to be supplied to a pressure receiving chamber of the piston, thereby causing the piston to move to the position of abutment with the stopper.
Patent
Isolation valve with corrosion protected and heat transfer enhanced valve actuator and closure apparatus and method
TL;DR: An isolation valve (10) includes a shield (130) that surrounds and protects the valve closure actuator components from exposure to corrosive fluids that flow through the valve when the valve is open as mentioned in this paper.
Patent
Flow control valve that may be used for mold temperature control systems
TL;DR: In this article, a valve is formed to resist snap-action closure forces and provide a smooth closing action to minimize or eliminate water hammer by modulating the relative air pressures above and below a piston in the valve.
Patent
Clean line heated valve
TL;DR: A valve of cleanable design capable of maintaining unfavourable conditions for microbial activity on the downstream side and/or outlet of the valve, said valve comprising: a smooth and contoured body (5) with an integral upstream connector (1), downstream connector and defined fluid flow path; a flexible sealing membrane (9) being: (i) selectively moveable into contact with the valve body to close the valve; (ii) selectively operate out of contact with valve body, to open the valve and (iii) selectively operable to a range of positions to vary the flow
Patent
High vacuum valve
TL;DR: The high vacuum valve as mentioned in this paper is a valve housing with two ports connected to the valve housing so as to be arranged perpendicular relative to each other, and capable of being communicated with each other through the valve flow channel.
