Valves & Actuator

Electro-hydraulic/ pneumatic control single/double slide valve







Electro-Hydraulic Pneumatic Control Slide valve is a kind of auto control valve for the use of regulating the flow of fluid status solid granule. The medium is high temperature gas with tiny solid granule. The valve has the features of high precision, rapid response and high dependability etc. It is widely used in the catalytic cracking unit of petroleum refinery, also in other occasions with similar condition. 

The Control Part: The valve body and electro-hydraulic actuator meet international general UOP standard.


Electro-hydraulic/pneumatic control high/low temperature butterfly valve




Electro-hydraulic/pneumatic control high/low temperature butterfly valve is an auto control valve, which has the properties of high precision, large output torque, rapid response, steady operation and high dependability. As controlling the flow of high temperature gas, it is widely used on the catalytic cracking unit in petroleum refinery, also used in other occasions which have similar condition.


Electric high temperature gate valve




Electric high temperature gate valve is an auto switch valve on the high temp gas flow pipeline with slight amount solid particles. It has the advantages of long life, low maintenance cost, small currency resistance, high temperature resistant, anti-scour and anti-fraying. The structure is tandem type double stuffing which has the features of high hardness, wide sealing surface, the special seal with steam-tight annular and lip seal, flange connection.



Electro Hydraulic Pneumatic Control Plug Valve





Electro hydraulic pneumatic control plug valve is a kind of auto control valve, which can regulate the flow of solid granule. To resist high temperature medium flushing, the head and seat of valve are lined with anti-wear nonmetal. The valve is usually equipped at the bottom of vertical pipe path to control the flow of fluid status solid granule. It is widely used on the catalytic cracking unit in petroleum refinery or other occasions with same demand.


High Temperature Plate Gate Valve




The high temperature plate gate valve is kind of large stopping valve,which is used in the energy recovering system of catalytic cracking unit at petroleum refinery.lt is installed vertically on the horizontal pipe in front of high temperature butterfly valve.During the normal operation of the expander the valve is fully opened.In the shutdown or emergency state it can be closed by pneumatic actuating device to stop the stack gas flow,ensuring the safety of the expander and maintenance of the unti.


Triple eccentric hard seal high temperature butterfly valve




Triple eccentric hard seal high temperature butterfly valve is key equipment for the oil refineries as a means of shutoff or regulating facility for high temperature pipelines, it is of corrosion -resistance, high temperature application, zero leakage and high resolution as well as quick response of open and close.


 

top and bottom unheading valves



 

Both top and bottom unheading valves are a kind of high temperature gate valves with metal seats, installed on the coke drum's top and bottom in place of the blind plates. These valves are easy to operate , environmental friendly ,and minimize the coke drum unheading hazards, and can substitute the exported ones in terms of its price.
