Double expanding gate valve pdf files

Gate valves work by inserting a rectangular gate or wedge into the path of a flowing fluid. Moreover, a partially open gate valve may suffer from vibration in which the valve may move from its assigned position. Also the gate and seat may be subject to excessive wear if the valve is partially open. From 95 USD. Parallel Gate Valve. Thread Position of Valve Rod. Outside Gate Valve. Usage. Regulation, Safety, Emptying, Drain, Temperature Control, Flow Control. Standard. API 6A, API 6D, DIN, ISO. Application. Industrial Usage, Water Industrial Usage, Household Usage. Vatac designs and manufactures a broad line of through conduit slab gate valves and double expanding gate valves to satisfy the long distance transportation ATV supplies to the offshore industry a full range of valves and actuators that can operate at great ocean depths (deep and ultra-deep waters, up to 3.000 m) with working pressure up to 20000 psi. Moreover, ATV offers a full range of valves for hydrocarbons processing, for pipeline applications and Search for: Group / Through Conduit Double Expanding Gate Valves. - Single and double expanding gate valves. - Bolted bonnet, pressure seal and cryogenic designs are available. Valve is provided with a pneumatic piston and solenoid valve in such a way that when a closing signal is received in the solenoid valve the air in the pneumatic piston is released starting the BEL Valves' Through Conduit Expanding Gate Valve enables double block and bleed (DBB) functionality to be achieved within one single valve assembly, as opposed to the two conventional slab gates that would otherwise be required. The benefits include an overall cost The expanding gate valve does not require line pressure to seal and is recommended when a tight mechanical seal The design provides a mechanical seal between the seats and the gate in both high and low Valves are with Double Block and bleed feature.
