DEENPU Expanding Gate Valve Model M — flanged and threaded ends, parallel expanding gate, API 6A

Product Overview

The DEENPU expanding gate valve, Model M, is a parallel gate valve designed for drilling and production operations where dependable bidirectional sealing is required at working pressures from 2000 to 5000 PSI. When the gate is seated, the mechanical expansion of the two gate halves presses simultaneously against both seats, producing a positive metal-to-metal seal independent of line pressure.

Bodies are furnished in flanged or threaded end connections to API 6A, in sizes 2 1/16 in through 4 1/16 in. The expanding gate action prevents seat loading while the valve is being operated, keeping operating torque low and extending seat and gate service life in abrasive mud and production flowline service.

Key Features

Parallel expanding gate gives a positive seal at both low and high differential pressure
Bidirectional sealing — full rating in either flow direction
Gate floats away from seats during travel, minimizing wear and operating torque
Flanged (API 6A) or threaded end connections, 2 1/16″ – 4 1/16″
Working pressure 2000 / 3000 / 5000 PSI per API 6A flanged and threaded dimension tables
Seat faces and gates available in tungsten carbide hardfacing for abrasive service

Frequently Asked Questions

Q: What is the difference between an expanding gate valve and a slab gate valve?

A: An expanding gate valve uses a two-piece gate that mechanically spreads against both seats when closed, giving a positive seal even at low pressure. A slab gate relies on line pressure to press a single gate against the downstream seat. Expanding gates are preferred where low-pressure sealing matters.

Q: Can the valve be repaired in the field?

A: Yes. Seats, gates, stem packing and seals are replaceable; the valve body design allows seat removal without special machining. DEENPU supplies complete repair kits.

Q: Which pressure ratings are available?

A: Model M covers 2000, 3000 and 5000 PSI working pressure in sizes from 2 1/16″ to 4 1/16″ per the API 6A dimension tables shown on this page.
