A dual trip manifold assembly (TMA) includes an isolation valve assembly having a first valve configured to receive a flow of fluid from a hydraulic system fluid supply. The first valve is configured to channel the flow of fluid to at least one hydraulic circuit. The isolation valve assembly also includes a second valve configured to receive the flow of fluid from the at least one hydraulic circuit of the at least two hydraulic circuits. The second valve is further configured to channel the fluid flow to a trip header and to receive the fluid flow from the trip header. The first valve and the second valve are synchronized to each other such that rotation of one of said first and second valves causes a substantially similar rotation in the other of said first and second valves header.

Pressure independent flow rate control valve, for placement in hydraulic systems between upstream inlet and downstream outlet ducts, including a first functional unit arranged between the inlet and outlet ducts, mobile equipment actuated manually or by an actuator for setting and modifying the orifice span of a fluid passage, and thus the valve flow rate, up to complete closure; and a second functional unit for maintaining the differential pressure constant between upstream and downstream of the first unit, and thus the set valve flow rate independently of pressure fluctuations in the hydraulic system. The mobile equipment includes main equipment and secondary equipment which can linearly translate with respect to the main equipment for presetting the maximum valve flow rate, the main equipment carrying integrally the secondary equipment and being linearly displaced by the actuator for modulating the fluid flow rate from the preset maximum one up to complete closure.

A fluid transfer system includes a transfer device coupled to a dry break coupler. The transfer device includes a valve assembly moveable between an open and a closed position. The valve assembly includes a main valve and a pilot valve. An actuator controls both the main valve and the pilot valve. A cam plate interconnects the actuator and the valve assembly. The cam plate provides a quick acting shutoff to quickly move the valve assembly to the closed position. A pivotal and rotatable connector couples the transfer device to the dry break coupler. A lock is integrated with the actuator to lock the valve assembly in the closed position.

A heater assembly can be used with a gas appliance. The gas appliance can be a dual fuel appliance for use with one of a first fuel type or a second fuel type different than the first. The heater assembly can include at least one pressure regulator, a housing, and an actuation member. The housing has a first fuel hook-up for connecting the first fuel type to the heater assembly, a second fuel hook-up for connecting the second fuel type to the heater assembly, and an internal valve. The actuation member can control the position of the internal valve based on whether the first or the second fuel hook-up is used.

Provided is a steam valve (1) equipped with: a stop valve (2) capable of stopping/releasing the flow of steam when driven so as to open/close; an governing valve (3) that is provided coaxially in the interior of the stop valve (2), and that controls the flow volume of the steam when driven to open/close in the same direction as the opening/closing of the stop valve (2); and a first guide part (11) that is provided between the stop valve (2) and the governing valve (3) so as to separate the stop valve and the governing valve in the radial direction, and that guides at least the governing valve in the opening/closing direction.
