Introduction

Quality is our commitment, while competitive price and timely delivery is our promise.

From the beginning, the DHV name has become associated with quality in every step of our

manufacturing process. For the past decades our customers worldwide have trusted us to pro-

vide them with consistent and reliable valve products in their most severe and critical service.

We at DHV are proud of our ability to meet the stringent requirements of Refining, Gas/Oil, Pipeline,

Petrochemical and Power Plant.

DHV Ball Valves are designed, manufactured and tested to the latest manufacturing specificati-

ons of the American & International Standards Organizations. We welcome your challenges and

look forward to serving your critical project needs.

Uni-directional design

The live-loaded packing design allows the packing to maintain compression force compensation during drastic changes in tempera-ture, pressure and packing wear. This ensures excellent sealing performance and extends the life of the packing.

Extended bonnet distances the stuffing box away from the cryo-genic area, and aids in prevention of stem sealing failure due to low temperature.

Drip plate design for thermal transfer and containment of condensation.

Cavity relief hole is posi-tioned upstream when the valve is in the closed position, preventing abnor-mal cavity pressure increase caused by temperature variation.

High-precision bearing prevents the stem from galling and also reduces operating torque.

General Note: Structure shown in the picture is only typical structure, we can provide a variety of structures according to customer requirements, such as metal seated structure.

Extended bonnet distances the stuffing box away from the cryogenic area, and aids in prevention of stem sealing failure due to low temperature.


Blowoutproof stem


Excellent PCTFE / PAI seat seal

SPE seat only for example, DPE seat can be provided upon request

Fire-safe design to API 6FA, API 607

DHV cryogenic trunnion mounted ball valves have two seals- PTFE and graphite in both stem seal and body seal, makes the valve in compliance with ISO 15848-1 and MESC SPE 77/200 minimized fugitive emissions(class AH), and also in compliance with API 6FA, API 607 fire-safe test.


The live-loaded packing design allows the packing to maintain compression force compensation during drastic changes in temperature, pressure and packing wear. This ensures excellent sealing performance and extends the life of the packing.
