Stargate-O-Port valve (model # 6701a)
Designed to eliminate the inherent dangers of current feeding and outlet systems used in coke manufacturing, the Stargate-O-Port valve (model # 6701a) is a 60-in. 300# service valve with inlet flange and injectors for the feed media. It can handle temperatures up to 1,000°F and pressures to 400 psi. Alloy steel is used for the for the valve body and the blade is coated with nickel phosphorous to minimize the adhesion of coke to the blade, thus guaranteeing proper actuation of the valve. The blade is guided in graphite blade guides and sealed with exfoliated graphite. The seats are made of a specially treated graphite that does not allow gases to pass through internal porosity.

Stargate-O-Port valve
The Stargate-O-Port valve, a type of slide-gate valve or through-port valve, is characterized by having a well-guided blade that passes through both ends of the valve body. Constructed with a hole in the middle of this blade, these valves can process solids, liquids and gases within flow media. Designed to require neither lubrication nor maintenance, the valve can be used as a shut-off valve, flow control valve or a line blind. Even in a partially open position, the valve has a straight flow direction. Without a preferential flow direction, these valves can be installed in any position in the pipe.
