    1. H2 Positive Choke ValveThe H2 positive choke valve realized throttling via the oil nipple. We provide the oil nipple in various specifications to cater for different requirements of customers.
    1. H2 Adjustable Choke Valve

      The H2 adjustable choke valve is commonly used by petroleum equipment for flow control. The flow is adjustable via the needle and the seat, and it will be locked once the required flow rate is reached.

    1. Orifice Control Choke Valve Different from the H2 positive and adjustable throttles, it adopts two pieces of rotated hard alloy plates for flow regulation. The plates can be designed with open holes of different specifications upon the actual needs, so the optimal and maximal throttling diameter can be reached.
      Except the high-rigidity hard alloy plate and seat, the orifice control choke valve is also inlaid with hard alloy cover inside the outlet. Thus, the possibility of body damage caused by fluid erosion is greatly reduced, and the product life is prolonged.

Choke Valve

Overall Descriptions
The choke valve is a desirable product extensively applied to wellheads, manifold production, choke and kill manifolds, wellhead tests and other operations. It is a standardized throttle with multi-stage pressure cut-off and base, especially suitable for straddle-type erosive and corrosive working conditions. The pressure rating reaches up to 15000PSI.

Ready-Made Configurations
1. The positive choke throttle comes with a big oil nipple that has fixed liquid flow conditions.
2. The adjustable choke throttle enables variable flow rate that can be locked once meeting certain requirement.
3. The orifice control choke valve is the optimal one fit for long-term use. It is optionally positive or adjustable. The adjustable type adopts the needle and the seat for flow regulation, and the positive type adopts the positive orifice nipple for flow control. Once the required flow rate is reached, the orifice control throttle will be used as the positive choke throttle. Thus, the abrasion of flutter and main throttles is greatly reduced.

Features and Advantages
1. This product is highlighted by long life span and less maintenance.
2. There are holes on the cap nut for pressure discharge.
3. The cap nut is flanged and forged.
4. Except the O-ring sealing, body-to-cover contact is provided for preventing loose sealing.
5. Due to the pressure-discharging throttle, the pressure inside the cavity can be safely exhausted.

New Features
1. The choke valve is designed and manufactured totally conforming to API 6A standards and has passed the approval test of PR2 throttle.
2. It comes with a forged body.
3. Both operation and maintenance are easy and convenient.
