Camtech Through Conduit Gate valves offer increased value by incorporating advanced design features. These valves are designs and manufactured with a full bore port, rising stem, OS & Y type with floating seats. These valves are robust in construction and easy In-Line maintainability. The full port bi-directional flow capability minimizes pressure drop and turbulence. The expanding gate valve does not require line pressure to seal and is recommended when a tight mechanical seal is required. The design provides a mechanical seal between the seats and the gate in both high and low pressure applications. There are two piece wedged shape assembly consisting of a Gate and a Segment. The Gate is attached and driven by the stem. Positive sealing is achieved in both high and low pressure conditions by expanding the Gate and the Segment out towards the seats while in a closed position.
The valve seat faces are outside the flow stream and therefore the seats are protected from the erosive action of the fluid flow. These valves are piggable valves and Pigs and scrapers can be run through the valve without causing damage to the valve and seats. Through Conduit valves are primarily used in chemical, petrochemical and oil & gas transmission pipelines, onshore terminals, offshore platforms, Suitable for all types of fluids (including abrasive fluids). Few silent features are indicated as below,
Valves are with Double Block and bleed feature.
These valves are fire safe as per API 6FA.
Emergency Seat and Stem sealant injectors are provided.
Stem seal offers tight seal with little to no maintenance over long periods of time.
Non Rotating stem design.
Hardfaced seating faces resist erosion.
Soft seat valves are Bubble tight shut off over extended period of service.
Low emission packing set available for special service.
Drain and Vent are provided as standard features with cavity relief valve.
