Description
DEENPU FC Gate Valve is a heavy-duty slab gate valve engineered for high-pressure oilfield and flowline applications. Designed and manufactured to meet API 6A specification, the FC gate valve delivers reliable, bi-directional shut-off performance in the most demanding drilling and production environments. Its full-bore thru-conduit design and one-piece gate prevent sediment buildup and pressure locks, ensuring long service life with minimal maintenance.
With a non-rising stem, metal-to-metal sealing, floating seat rings, and a field-repairable in-line design, the DEENPU FC gate valve is the preferred choice for drilling manifolds, Christmas trees, and severe service applications. All critical body and trim materials are available in NACE MR0175 / ISO 15156 compliant grades to handle sour-service (H₂S) environments.
Key Features
- Full-bore thru-conduit design eliminates particle collection and extends service life
- Floating slab gate and seats produce positive pressure-energized seal
- One-piece gate prevents line sediment from entering body cavity and prevents pressure locks
- Bi-directional sealing with non-rising stem
- Metal-to-metal seals at body/bonnet, gate/seat ring/body bushing, body/body bushing interfaces
- Gate and seat overlaid with Tungsten Carbide for superior wear resistance
- Forged steel valve bodies and bonnets for high-pressure integrity
- In-line repairability — seats, body bushings, gate, and stem replaceable in the field
- Stem packing can be replaced under pressure via back-seat capability
- Metal-to-metal backseat contains body pressure if stem packing leaks
- Block and Bleed mechanism available for safe pressure relief
- Compatible with hydraulic actuators for manifold or subsea service

How It Works
The FC gate valve operates using a slab gate that moves perpendicular to the flow path via a non-rising stem turned by the handwheel. When the gate is fully retracted, the full-bore opening provides unobstructed flow through the valve — minimizing pressure drop and eliminating turbulence. When closed, the gate is wedged between two floating seat rings, creating a bi-directional metal-to-metal seal that resists both upstream and downstream pressure.
The floating seat design equalizes body pressure across the seat ring/body bushing interface, eliminating body erosion in the seat pockets. The metal-to-metal backseat provides a secondary seal, allowing stem packing to be replaced under pressure without leaking product to atmosphere. For remote or automated operations, the manual handwheel can be replaced with a hydraulic actuator.
