Pilot Operated Solenoid Valves

The pilot operated solenoid valve is mainly used for residence and small-scale business project for its sturdiness, durability, simple operation and reliable performance. The product is classified into three types with manual control, without manual control, and with flow control functions, respectively. Each type of product can be matched with the irrigation solenoid of S391 series with plastic packaging and S392 series with metal casing manufactured by our company.

Features
1. The pilot operated solenoid valve body is made of anti-aging reinforced nylon material. So, the service life of the product is longer.
2. The diaphragm is made of synthetic rubber, which is much more durable.
3. Designed in pilot operated valve body structure, the product has the function of self cleaning. For the water with impurities, the product will not be clogged.
4. With the unique thread bonnet, the cleaning and maintenance for this product is easy.
5. The rate of flow is big while the pressure drop is small.

Advantages of Centralized Procurement
As a professional manufacturer for hydraulic solenoid and solenoid valve, we suggest our customer to purchase the products from one supplier for the following reasons.
1. The favorable price. Generally, the supplier will offer a good price for the big order.
2. Delivery time. If customer purchases two kinds of products from one supplier, the supplier will reasonably arrange the production scheduling to ensure the delivery time. Meanwhile, it will cost less to send the items together than to deliver the products separately by different suppliers.
3. Quality guarantee. Generally, it is much easier for the supplier to find the problem because they can conduct overall test on the products. Being familiar with their own products, they can find the cause for the problem easily. This is a great guarantee to the quality of the product. Even customers find the problem with the products, it is much easier for them to contact with one supplier than to contact with different suppliers.
4. Professionalism. A supplier manufacturing both valves and solenoids may offer you more help and suggestion on the products in case you have any trouble. With complete support from the supplier, you can make better use of the product.
