Stainless Valve Company has been making quality valves for over 25 years. They are located in Monroe, North Carolina. Their facilities are close to several Interstates, so they can utilize a vast array of shipping resources. They have exclusively designed and implemented the Stargate-O- Port valves. Their company's determination is to provide their customers with the best advice, assistance and products available. They are staffed with professional valve designers and builders to carry out this determination. They strive to provide excellent professional service with a personal touch and have successfully satisfied customers on a national and international scale. This is due to everyone in the company being attentive to the needs stipulated by their customers.
SVC Big Valves
Their generic terms are: (Slide gate valves, O-port gate valves or through port valves). Their design is rugged for applications with high temperature and pressure shock waves, aggressive flow media, liquids, gases and solids. Solids from the media cannot be pressed into the seat area preventing proper closing. This makes the SVC Big Valves the choice for handling solids in flow media. Valves can be installed in any position in the pipe, they do not have a preferential flow direction. The tightness of the shut off does not depend on a pressure differential between the upstream and downstream side.

Materials
Body, packing glands, and gate are manufactured of solid rolled Hastelloy, titanium, stainless steel 304, 316, 317, or 5M0254 (25-6) respectively. It is not cast or lined but solid plate to the thickness and with reinforcement required for the pressure rating and long maintenance-free service. |

Valve Seats
The double seats are solid filled PTFE for temperatures to 450 deg F. They are spring loaded for long lasting drip-tight shut off even with abrasive medium. For higher temperatures graphite seats are used.

Valve Actuators
 |
 |
The valves are actuated by type "A" pneumatic actuators, i.e., the top quality cylinders for longest life even at high cycle rates. The actuators are epoxy-painted; cylinder rods are stainless steel for corrosion resistance. The actuators on valves up to 18" are mounted in-line with the blade. For valves of 20" and above the actuators are mounted in tandem on the small sides of the valves, acting through crossbars attached to the blades. Hydraulic and electric actuators are available, as well as manual hand-wheel and gear operators. |
 |
Locking Devices
The valves are supplied with locking devices LC, for mechanically locking the valves in the closed position, preventing accidental opening of the valves. This allows work behind the locked valve without the necessity of setting blanks thus decreasing the downtime. The pin of the locking device is heavy enough to allow the valve actuators to be charged with 125 psi air pressure without damage to the locking device. The LO locking device for locking in the open position is available as an option.

Control Options
Micro limit switches, Go proximity switches or any other limit switch based on customer preference indicating open or closed position are provided. Also, the supply of solenoid valves to activate the cylinders is an option. They are mounted on the valve actuators and connected to the actuator ports. The solenoid valves and limit-switches are directly wired to the customer's control station. No control panel is required at the valves. |
